Abstract

본 발명은 3대역용 레이다 검출기에 있어서, 검출된 증폭부의 출력신호로 중가대역 발진부를 제어하는 기술에 관한 것으로, 혼안테나와 중간대역 증폭과정을 통해 검출된 중간주파수 신호와 대역에 따른 국부발진주파수를 중간대역 혼합부에서 혼한합 후 필터부와 FM검사부의 통해 복조한 신호를 증폭하는 제1, 제2증폭부와, 상기 제2증폭부로 부터 출력된 신호의 유, 무에 따라 절환되어 대역을 선택하는 대역선택부와, 일정레벨의 클럭펄스신호를 발생하는 클럭발생부와, 상기 대역선택부로 부터 출력된 신호레벨 및 클럭발생부의 클럭펄스에 따라 대역선택 스위칭부가 구동을 하여 제1, 제2중간대역 국부발진부를 선택 조정하도록 한 것이다.The present invention relates to a technique for controlling a mid-band oscillator with an output signal of a detected amplification unit in a three-band radar detector. Is mixed according to whether the first and second amplifiers amplify the demodulated signal through the filter unit and the FM test unit, and whether or not the signal output from the second amplifier unit is mixed. The band selector selects, the clock generator generates a predetermined level of clock pulse signal, and the band selector switches the first and second drives according to the signal level output from the band selector and the clock pulse of the clock generator. The intermediate band local oscillator is selected and adjusted.
