航管一次雷达接收/信号产生子系统

航空管制一次雷达主要用于航路空域监视,要求威力大、盲区小、可靠性高,同时探测空中降水分布,引导飞机避开气象危险区。文中介绍了一种航空管制一次雷达接收/信号产生子系统设计,采用了宽、窄双模式波形,单通道频率分集,独立气象通道,双套热冗余及在线定量监测等技术,重点解决宽空间探测范围覆盖、高目标检测概率、兼容气象探测和雷达的高可靠等问题。文中最后给出了研制结果,并进入试值勤应用阶段,取得较满意的效果。

A Receiver and Signal Generating Subsystem for ATC Primary Surveillance Radar

ATC primary surveillance radar is mainly used in the aerial surveillance though the airway,which requires large coverage,small dead zone,high reliability.Meanwhile it can detect the aerial distribution of precipitation,and guide the aircraft to avoid the meteorological hazardous area.A design of a receiver and signal generating subsystem for ATC primary surveillance radar is described in detail in this paper.The system has employed a great deal of technologies such as broad and narrow dual-mode waveform,sin...
