Abstract
전차 탑재 레이더는 기상에 관계없이 전천후로 대전차 미사일을 탐지하는 능동 방호 장치의 필수적인 센서이다. 본 논문에서는 전차 탑재 레이더의 설계, 제작 및 시험 결과를 제시한다. 레이더 시스템은 안테나부, 송수신부, 신호처리부의 3개의 LRU로 구성되며, 개발 기술은 패치 안테나, SSPA 송신기, coherent I/Q detector, DSP기반 도플러 FFT 필터, 적응 CFAR, TWS 추적기 및 위협 판단을 포함한다. 개발된 레이더 시스템의 설계 성능은 고정 및 기동 시험을 통하여 확인한다. A Missile Warning Radar is an essential sensor for active protection system to detect antitank missile in all weather environments. This paper presents the design, development, and test results of L-band pulsed Doppler radar system for main battle tank. This radar system consists of 3 LRUs, which include antenna unit, transmitter and receiver unit and radar signal & data processing unit. The developed core technologies include the patch antenna, SSPA transmitter, coherent I/Q detector, DSP based Doppler FFT filter, adaptive CFAR, SIW tracking capability, and threat decision. The design performance of the developed radar system is verified through various ground fixed and moving vehicle test.
