K p\u00e1smo.. K band.. \u010do, ako a pre\u010do<\/p>\n

Ak u\u017e bolo spomenut\u00e9 v \u010dl\u00e1nku RADAR – Dopplerove mera\u010de r\u00fdchlosti, radary m\u00f4\u017eu pracova\u0165 vo viacern\u00fdch p\u00e1smach teda na roznych frekvenci\u00e1ch. Ka p\u00e1smo ktor\u00e9 je pou\u017e\u00edvan\u00e9 aj u n\u00e1s m\u00e1 ve\u013ek\u00fa v\u00fdhodu preto\u017ee v tomto p\u00e1sme nepracuj\u00fa \u017eiadne in\u00e9 zariadenia. Z tejto skuto\u010dnosti vypl\u00fdva, \u017ee detektor bude vykazova\u0165 len ve\u013emi mal\u00e9 mno\u017estvo falo\u0161n\u00fdch poplachov. Vo v\u00e4\u010d\u0161ine kraj\u00edn sa v\u0161ak pou\u017e\u00edva okrem Ka p\u00e1sma aj K p\u00e1smo a tu nast\u00e1vaj\u00fa nepr\u00edjemnosti. Z\u00e1kladn\u00fd princ\u00edp funkcie radaru je s\u00edce nez\u00e1visl\u00fd na pou\u017eitom p\u00e1sme, ale probl\u00e9m K p\u00e1sma sp\u00f4sobuje skuto\u010dnos\u0165, \u017ee v rovnakom p\u00e1sme pracuj\u00fa aj automatick\u00e9 otv\u00e1ra\u010de dver\u00ed ktor\u00e9 n\u00e1jdete na benz\u00ednov\u00fdch pump\u00e1ch, obchodoch, \u00faradoch a pod. Ked\u017ee detektor nem\u00e1 ako rozl\u00ed\u0161i\u0165 \u010di dan\u00e9 mikrovlnn\u00e9 \u017eiarenie poch\u00e1dza zo skuto\u010dn\u00e9ho radaru alebo nie, v\u00fdsledkom s\u00fa pomerne \u010dast\u00e9 falo\u0161n\u00e9 poplachy predov\u0161etk\u00fdm pri jazde v mest\u00e1ch a na dialniciach okolo benz\u00ednov\u00fdch p\u00famp.<\/p>\n

\"\"Dnes ale existuje aj na tento probl\u00e9m viacero sp\u00f4sobov rie\u0161enia aj ke\u010f samozrejme nie s\u00fa \u00faplne dokonal\u00e9. Niektor\u00e9 radarov\u00e9 detektory vybaven\u00e9 GPS sn\u00edma\u010dom umo\u017e\u0148uj\u00fa vodi\u010dovi v\u010faka funkcii zalo\u017eenej na kombin\u00e1ci\u00ed GPS lokality a zaznamenanej frekvencie automaticky st\u00ed\u0161i\u0165 zvukov\u00fa signaliz\u00e1ciu pri pravidelnom prejazde miestom s falo\u0161n\u00fdm poplachom napr\u00edklad pri ceste do pr\u00e1ce. V\u010faka ulo\u017eeniu frekvencie by mal by\u0165 vodi\u010d v pr\u00edpade pr\u00edtomnosti skuto\u010dn\u00e9ho radaru v mieste falo\u0161n\u00e9ho poplachu na tento radar upozornen\u00fd. Nie je to v\u0161ak take jednoduch\u00e9 preto\u017ee detektory v skuto\u010dnosti odfiltruj\u00fa nie presne frekvenciu falo\u0161n\u00e9ho poplachu ale aj u\u017e\u0161ie p\u00e1sme okolo neho. M\u00f4\u017ee teda nasta\u0165 situ\u00e1cia kedy pri odfiltrovan\u00ed falo\u0161n\u00e9ho poplachu v K p\u00e1sme nebude vodi\u010d pri nasleduj\u00facom prejazde dan\u00fdm miestom s v\u00fdskytom zdroja falo\u0161n\u00e9ho poplachu upozornen\u00fd na falo\u0161n\u00fd poplach, ale ani na pr\u00edpadn\u00fd radar pracuj\u00faci v K p\u00e1sme v tej istej oblasti. Toto samozrejme plat\u00ed len za predpokladu, \u017ee frekvencia radaru a zdroja falo\u0161n\u00e9ho poplachu bud\u00fa v r\u00e1mci spomenut\u00e9ho bloku.<\/p>\n

Okrem toho existuj\u00fa aj \u0161peci\u00e1lne citlivostn\u00e9 re\u017eimy ktor\u00e9 eliminuj\u00fa falo\u0161ne poplachy automaticky aj bez GPS \u00fadajov. Ich \u00fa\u010dinnos\u0165 v\u0161ak m\u00f4\u017ee by\u0165 v z\u00e1vislosti od okolnost\u00ed o nie\u010do ni\u017e\u0161ia. Niektor\u00e9 funkcie zase eliminuje v\u0161etky poplachy pokia\u013e je r\u00fdchlos\u0165 jazdy ni\u017e\u0161ia ako stanoven\u00e1. T\u00e1to n\u00e1jde uplatnenie napr\u00edklad pri parkovan\u00ed v bl\u00edzkosti obchodov kde je be\u017ene ve\u013ek\u00e9 mno\u017estvo zdrojov falo\u0161n\u00fdch poplachov, alebo jednoducho v situ\u00e1cii kedy jazd\u00edte pomaly.<\/p>\n

Medzi \u010fal\u0161ie met\u00f3dy patr\u00ed rozdelenie K p\u00e1sma do blokov a zn\u00ed\u017eenie citlivosti alebo \u00fapln\u00e9 st\u00ed\u0161enie upozornenia na sign\u00e1ly v jednotliv\u00fdch blokoch podla \u017eelania u\u017e\u00edvate\u013ea. Toto by malo by\u0165 samozrejme reflektova\u0165 p\u00e1sma na ktor\u00fdch v danom regi\u00f3ne pracuj\u00fa skuto\u010dn\u00e9 radary.<\/p>\n

U niektor\u00fdch detektorov existuje re\u017eim ktor\u00fd eliminuje len ve\u013emi slab\u00e9 p\u00e1ry sign\u00e1lov. P\u00e1ry z toho d\u00f4vodu, \u017ee automatick\u00e9 senzory sl\u00fa\u017eiace na otv\u00e1ranie dver\u00ed s\u00fa in\u0161talovan\u00e9 v\u017edy v p\u00e1roch, teda jeden z vn\u00fatornej a jeden z vonkaj\u0161ej strany dver\u00ed. Detektory inej zna\u010dky zase dovo\u013euj\u00fa nastavi\u0165 po akej dobe od zachytenia sign\u00e1lu v K p\u00e1sme spust\u00ed detektor poplach resp intenzitu sign\u00e1lu pri ktorej bude poplach vyvolan\u00fd okam\u017eite bez oh\u013eadu nato, \u010di u\u017e uplynul stanoven\u00fd \u010das.<\/p>\n

\"\"V posledn\u00fdch rokoch sa vo v\u00e4\u010d\u0161ej miere za\u010d\u00ednaj\u00fa pou\u017e\u00edva\u0165 aj r\u00f4zne 2D a 3D radary. Ich v\u00fdhodou z h\u013eadiska elimin\u00e1cie falo\u0161n\u00fdch poplachov je skuto\u010dnos\u0165, \u017ee detektor so spr\u00e1vnym softv\u00e9rom m\u00e1 mo\u017enos\u0165 ich odl\u00ed\u0161\u00ed\u0165 od in\u00fdch zdrojov sign\u00e1lu pracuj\u00facich v K p\u00e1sme. To teda znamen\u00e1, \u017ee je mo\u017en\u00e9 aby detektor reagoval iba na tieto konkr\u00e9tne radary a pritom ignoroval v\u0161etky ostatn\u00e9 zdroje a t\u00fdm teda aj v\u0161etky falo\u0161n\u00e9 poplachy. To samozrejme predpoklad\u00e1, \u017ee v danej oblasti pou\u017e\u00edva pol\u00edcia v\u00fdlu\u010dne spom\u00ednan\u00e9 radary novej gener\u00e1cie.<\/p>\n

Niektor\u00e9 radary pracuj\u00fa v takzvanom pulznom re\u017eime kedy mikrovlnn\u00e9 \u017eiarenie nie je vy\u017earovan\u00e9 kontinu\u00e1lne ale syst\u00e9mom XXms vysielanie \u2013 XXms pauza \u2013 XXms vysielanie a tak \u010falej st\u00e1le dookola. V\u00fdsledkom pou\u017eitia pulzn\u00e9ho re\u017eimu je fakt, \u017ee viacero antiradarov tieto radary nezachyt\u00ed v\u00f4bec alebo len sporadicky preto\u017ee ich pova\u017euje za falo\u0161n\u00fd poplach.<\/p>\n
