摘要: 分布式孔径相参合成雷达通过多雷达相参合成联合探测,巧妙解决了雷达大威力探测与机动性之间的矛盾,具有生存能力强、效费比高、角分辨率高、扩展性强和实现性好等诸多优势,可应用于防空反导、精密测量和空间目标监视等领域,适用于车载、舰载、机载和弹载等多个平台。针对分布式孔径相参合成雷达系统设计较传统雷达更为复杂,影响因素更多的情况,从雷达个数选择、基线长度选择和频段选择等方面给出了分布式孔径相参合成雷达系统设计需考虑的因素和设计准则。在此基础上,提出了分布式孔径相参合成雷达系统拓扑结构并给出了相参合成目标探测流程设计。通过雷达原理样机对飞机目标和实装雷达改造对卫星目标开展的相参合成探测试验,验证了分布式孔径相参合成雷达系统设计的正确性与工程可实现性。

Abstract: By multi-radar coherence-synthetic detection, distributed aperture coherence-synthetic radar cleverly solves the contradictions between the radar great power detection and mobility, which has the advantage of strong survival ability, high cost-effectiveness ratio, high angular accuracy, strong expandability and easy realization, and so on; it can also be used in the air defense and anti missile, precision measurement and space target monitoring and other fields, suitable to the vehicle, shipborne, airborne, bombs and other platforms. The design of distributed aperture coherence synthetic radar system is more complex than traditional radar. The design consideration factors and design criteria from the radar number selecting, baseline length selecting, frequency selecting and other side for the distributed aperture coherence synthetic radar system are given. The distributed aperture coherence synthetic radar system topology is presented and the design of coherence synthetic target detection processing is proposed. Through the coherence synthetic detection experiments carried out on the aircraft and satellite targets by the radar prototype and radar equipment, the correctness of the distributed aperture coherence synthetic radar system design and the project feasibility are verified.
