Ireda

Ku-radar systems, abakwa-Detar Ngokukhethekile, amasiginali we-RF afudumele aphezulu akhishwe yi-radar evutha amagagasi asakazekile kulitshe, futhi ngemuva kwalezi zimpawu zama-echo waveform atholakele, ukulungiswa kwe-demoral demoral kudinga ukwenziwa ngomtshina. Umtshina uguqula ushintsho e-amplitude nasezivalekeni ze-RF eziphezulu ze-RF kuma-DC noma ama-litter-frequency kagesi kagesi wokucubungula okulandelayo kwesiginali.

Umtshina empeleni uyingxenye yemodyuli esebenzayo endleleni yokuthola iRadar, ikakhulukazi kufaka phakathi i-amplifier yesiginali, i-mixer, i-oscillator yasendaweni, ukuhlunga kanye ne-amplifier ekwakhiwe isitholi se-ECHO Signal. Phakathi kwazo, i-oscillator yendawo ingasetjenziswa njengomthombo wesiginali wesethenjwa (i-oscillator yasendaweni, bheka) ukuhlinzeka ngesiginali yokuxuba okuxubile, futhi izihlungi kanye nama-amplifiers asetshenziselwa ukuhlunga okubuthakathaka kwemibutha noma uma kukhuliswa kwesiginali. Ngakho-ke, umtshina udlala indima ebalulekile ohlelweni lwe-radar, futhi ukusebenza kwawo nokuqina okusebenzayo kuthinta ngqo ukutholwa kanye nokulandela amandla okulandela uhlelo lwe-radar.
