Radar - chii ichocho? Pfungwa yekushanda

Radar is compact electronic gadget iyo inokwanisa kuona nekuudza muridzi wacho pamusoro pekuvapo kwehutachiona hwemapurisa emigwagwa munguva yekufamba. Nheyo dzakadaro dzinobudisa mapurisa emasero kana mafungu eredhiyo, tsanangudzo iyo inotariswa. Iko ndiko kuti, radar ishoko rekugamuchira iro rinoshanda nemishumo inosvika.

Pano pane passive uye inoshanda mienzaniso. Izvozvo zvinonzi antiradars uye zvinonyanya kukosha ndeye chizvarwa chekuvhiringidzwa kwepamusoro-simba kweGIBDD kuongorora maitiro. Zvigadzirwa zvakadaro zvinoshanda mune imwe nhepfenyuro yevhepfenyuro yemitambo kana kuti kunyatsorongedza chiratidzo chekupindura, icho chinopfuura kupfuura simba rokutanga rokutakura.

Somugumisiro, pane zvishandiso / mapurisa emapurisa emigwagwa pachava nemugumisiro wekugadzirisa, kana kuti hapana chichazotevera. Rhadhira yakadaro inopesana zvakananga nemutemo, apo pane zvakanakisisa iwe unobhadharwa nekutorwa kwegadget, uye pamhosva yakaipisisa - mhosva. Nokudaro, hatingazvifungi, asi ngatitaurire pamusoro pemafambisirwo akaregererwa, ayo anonzi detectors.

Rimwe rinowanzogadziriswa-radar inogadziriswa isina kugadzirisa iyo inenge isingafadzi kana kuenzanisa zviratidzo kubva kuGIBDD's bearing direction systems, sekurwisa-radar, asi kungoita kuti muridzi wacho azive nezvekufamba kwavo / kuvapo.

Varikuita

Mumusika wemhando iyi yemidziyo yemotokari, mabhuku anopfuura gumi nemaviri ari kutungamirira. Pano unogona kuona iyo kambani Whistler, Escort, radar detector Sho Me, Cobra naBeltronix. Izvi, chaizvoizvo, ndiwo mushure wevakiki vane nhau yakanaka, iyo zita rave rave zita remhuri yezvigadzirwa zvemhando iyi.

Kune mamwe makambani mashoma anozivikanwa kwazvo, mumakwikwi ayo anouya mazano akangwara, asi apa unofanirwa kutarisisa uye kuyera zvakawanda vasati vatenga. Izvi zvinosanganisira "Uniden", radar STR (Street Storm), Rocky Mountain nePNI.

Kana iri yenharaunda yedu, mutengi wekumusha anoda zvinyorwa zvishoma kana zvishoma zvigadziriswa zvinyatsoenderana nemamiriro edu chaiwo kubva kuMongoose, Simikon, Nevedimka uye zvizvarwa zvekare zveCobra mastiff. Kurumidza kuwana kuwana mukurumbira muRussian Federation brand Radartech, ane mazano anogona kuona "Arrow" inozivikanwa zvikuru.

Iko kunewo makopi akawandisa emashiripiti akadaro, ayo emotokari uye chikamu chechimwe chinhu chakakosha hachisi kutamba, zvakadai semuenzaniso radar 24-Flight, inokwanisa kutevera nzira yeIndaneti ye ndege. Chinhu chacho chinobatsira mune dzimwe mamiriro ezvinhu, asiwo zvishoma nezvishoma zvakanyanya.

Pfungwa yekushanda

IGIBDD inotakura maitiro inoshanda maererano neurongwa hwekufungidzira, ndiko kuti, kukurumidza kunotaridzwa nemirairo inoratidzwa kubva mumotokari yako. Chiratidzo chakadaro chinonoka kudarika mutsara wakarurama, iyo inoshandisa radar detector, zvinoreva kuti mutyairi achaziviswa mberi kwekuvapo kwekutakura munguva yekufamba.

Kana mamiriro okunze akanaka, uyewo nzvimbo yacho, unogona kuwana mapurisa epamitemo iri kure nemamita 5000, uye radar yakanakisisa yepamusoro inokwanisa kubata chiratidzo uye kusvika mamita 10 000, kunyange munzvimbo yakasviba.

Tichifunga nezvekuti vazhinji vevatsvagi vemapurisa vakagadzirirwa mamita 300-500 kuti vadzidze zvakasimba, radar, iwe unogona kutaura, pasina kushungurudza, inokunyevera pamusoro pokuvapo kweDPS mushure.

Kune rimwewo rudzi rwemhando iyi yemichina - GPS-radar. Pano mutemo webasa wakasiyana zvachose. Kana iyo detector iri kushanda zvakananga nekutarira kushandiswa kweGIBDD, iyo GPS inofungisisa dota yemaroto, kureva, inonyatsojekesa nezvezvigadzirwa nemakamera nenzira yepamotokari pa-line.

Iyi radar inoda kugara (zvakanaka, kana pedyo nayo) kushamwaridzana nesetereti kuti ibudise dheedheni yakavimbika. Izvo zvakasiyana zvinonyatsoshanda, asi chete kana zviratidzo zvigadzikana uye hazviperi kwenguva yakareba, paunenge uchifamba munzira. Kana kushamwaridzana neSatellite kunowanzovhiringidzika kana pasina kana zvachose, ipapo iwe unongotora gadget yakaisvonaka pane jira, kwete radar.

Mhinduro dzeimba yezvipfeko zvakadaro dzakasiyana, uye dzinonyanya kutarisana nemamiriro ekunze emamiriro ekunze aya kana iyo. Iwe une nzvimbo yezuva uye yemasango - inenge ipi zvayo yezvinonzi radar detector yakakodzera, iwe unowanzofambisa mumakomo kana mumvura - iyo GPS ichava ndiyo nzira yakanakisisa.

Kana iri mhinduro pamusoro pemhando dzakasiyana-siyana dzeparadhadhi, zvakaoma zvikuru kuzvitsanangurira nekuda kwemhando dzakasiyana dzevakugadziri, mitsara, mutsara uye magadziri pachavo. Kunyange zvakadaro, zvinobvira kutsvaga chimiro chimwe chekuongororwa, iyo inonyatsoratidzwa nemashoko okuti: "Zvinodhura, zviri nani."

Amplifiers

Zvose radhiar-detectors (pamasasa emasasa), nemafungiro avo, vanoshandisa zviratidzo zvemashoko, izvo zvinowedzera huwandu hwekushanda kwavo. Pamwe chete, unogona kuratidza 2 maitiro ekusimudzira kwakadaro - zvakananga uye pachikonzero chesepanclerator (dzimwe nguva pamwe nechirevo chekutanga "super").

Tungamirira kukurudzira

Iyi ndiyo nzira yekare uye yakawanda yekuita bhajeti rekusimudzira kusimbisa. Chimwe chezvibatsiro zvemuitiro uyu ndechokusava nehanya, ndiko kuti, mazai emu module yacho pachawo anowedzera kusvika pazero. Munyika umo mudziyo wakadaro unorambidzwa, gadget ine yakagadzirisa yakadaro haifaniri chero mhando dzemitemo inodzivisa, yakadai seVG-2, iri mumotokari.

Mukuwedzera, kutungamirira kukurudzira kwe detector kunopedza kukanganisa kwakawanda, izvo zvinokonzerwa nekunzwisiswa zvishoma kwechigadzirwa. Zvirongwa zvepurogiramu yakadai zviri nyore kwazvo kugadzirisa uye kuva nekutonga kwemutengo mutengo.

Vashandi vekuEurope vave vatotanga kurega mataramiro akadaro, nekuda kwekushanda kwavo kwakadzika, asi vanoverengeka vekumba vanoramba vachingozadza motokari yemotokari nemagetsi nemagetsi akadaro.

Heterodyne amplifier

Iyi nzira yekusimudza inonyanya kufambira mberi uye yakanyanya kunyanya mumagetsi. Ma modules akadaro anowanzoonekwa mukati mebhajheji uye premium mienzaniso yevanonzi radar detectors. Kubviswa kusingagoneki kwekusimudzirwa kwakadaro ukuru hwekunzwisisa uye samuenzaniso wakanaka wekufambisa maitiro.

Chinokosha ndechokuti chigadziro chine module yakadai seheterodyne inoshanda, kureva kuti, radar inotanga kubudisa maitiro maitiro panguva yekushanda. Mukuwedzera, kuvapo kwekupindira panguva yekushandiswa dzimwe nguva kunopindira zvakanyanya basa rinowanzoshandiswa. Kugadzirisa chigadzirwa chakadaro chinoshanduka kuva chiitiko chaiyo pamwe nebazi rezvikwata zvakakomba uye kusarudzwa kwemaitiro.

Uyewo, inofanira kuve yakasiyana zvakananga kuti zvigadziro zveurongwa hwakadaro zvinorambidzwa nemutemo mune dzimwe nyika. Pamberi kweRussia maitiro akadaro asati asvika, saka munharaunda yedu heterodyne radar detector inogona kushandiswa pasina kutya kwekubhadharwa. Vanodhura zvigadzirwa zvakadaro zvishoma, asi, izvo zvinonyanya kukosha, kuripa nokukurumidza zvikuru, kunyanya kana iwe kazhinji uchienda mumigwagwa, autobahns uye kazhinji uchitenderera munyika.

Signal Processing Unit

Ichi chivako, muzvokwadi, ndiyo mwoyo weipi radar. Pano, zviratidzo zvinouya kubva kune antenna uye sensor zvinoshandiswa. Izvi zvinoreva kuti, kuvimba pane dzimwe nzira dzavo dzekugadzirisa, shanduro inoshandisa iyo mashoko uye inopa kumushandi nenzira yakakodzera. Nhasi, zvimwe zvakasiyana-siyana zvemashoko akadaro anoshandiswa anoshandiswa: analogue, digital uye hybrid.

Analog

Nzira yakareruka yeanorog nzira inononoka kuenda kune yakapfuura, kupa nzira kune zvimedu uye zvigadzirwa zvemagetsi. Kugadzirisa kwakadaro kunobva pane zvakatangwa zvirongwa mu chip, zvinoreva, maererano nemirairo yakatemwa.

Kukanganisa kuno kwakajeka uye kunotsoropodza: kuwedzerwa kwepamusoro kwekupindira uye kukanganisa, zvakaderera zvikuru nekukurumidza kushandiswa kwezvino.

Digital

Nzira ye digital inonyanya kuvimbiswa maererano neyunivhesiti. Radar-detectors zveurongwa hwakadaro dzakagadzirwa ne microprocessor uye yakawanda yeVLSIs (yakakura-yakawanda yakatenderedzwa), apo pane zvakawanda zvakasiyana-siyana zvekugadzirwa kwezviitiko pamwe neheti yezvigadziridzo zvakagadziridzwa, uye kushanda kwechigadzirwa chakadaro kunobva pane zvigadzirwa, izvo zvinobvumira kuwedzera kukurumidza kwechimbo kakawanda.

Iyo software inoshandiswa mudijadhi dzejedi inogona kugadziriswa, uye naizvozvo inovandudza kushanda kwe detector, kuwedzera zvinyorwa zvitsva kune zvekare zviripo urongwa. Mukuwedzera, iyo nzira inoratidzirwa nehuwandu hwenhema hunoita zviratidzo, uye kuwanda kwekupindira kunoderedzwa kusvika zero. Pano iwe unogona kuwedzera zvakanyanya kuwedzera kwekushanda kwekushanda uye kufanana kwekushandiswa (kusvika pamasere masere pamwe chete). Maererano nevatyairi, rudzi urwu rwezvigadzirwa zvinoshanda zvakanyanya kupfuura zvakafanana.

Hybrid

Zvigadzirwa zvemagetsi ndezvinyanya kuzivikanwa mundima yedu. Nheyo yekushanda kwechigadzirwa chakadaro chakajeka uye chinonzwisisika kubva pachirongwa. Icho chikonzero, tine mutezo wekare, asi nemikana ye "nhamba". Zvigadzirwa zvakadaro zvinoratidzirwa nekupindura zvakanyanya kana kuderera uye nhamba shomanana yezviratidzo zvenhema, kureva, kupindira.

Zvinenge zvese madhadhiro ari pamashalopu ezvinyorwa zvekudzivirira mukati-kati-bhajeti yemari vari kushanda pahuwandu hwemagetsi. Sezvo vazhinji vashandisi vanoti, "chimiro" ndechekuti, yakanaka, asi inodhura uye inofanira kushandiswa kakawanda, uye zviyo zvisinganzwisisiki uye zvakasiyana-siyana.
