一种应用脉冲多卜勒处理器对各种杂波区域进行自适应处理的全周态航空监视雷达(ASR)已经问世。这种脉冲多卜勒处理器能提供平滑的模拟视频回波信号,尤其在模拟视频方面,具有同时实现脉冲多卜勒处理高杂波中可见度(SCV)的优点和常规MTI良好方位精度的优点。采用全固态发射机带来的高可靠性和高可维修性,以及高SCV和良好的方位精度,这些都为空中交通管制(ATC)的安全性和有效性作出了保证。下面介绍信号处理器的设计原理和新型ASR的性能。
A full-cycle ASR with impulsive Doppler processors for adaptive processing of various clutter zones has emerged. This pulsed Doppler processor provides a smooth analog video echo signal, especially in analogue video, with the advantages of simultaneous pulsed Doppler processing of high in-clutter visibility (SCV) and the benefits of conventional MTI good azimuth accuracy . The high reliability and maintainability of all-solid-state transmitters combined with high SCV and good azimuth accuracy guarantee the safety and effectiveness of Air Traffic Control (ATC). The following describes the signal processor design principles and performance of the new ASR.
