脉冲雷达无法自跟踪问题的分析与解决

Analysis and Solution of Pulse Radar System′s Unable Auto-tracking Problem

首先简述了雷达跟踪问题的现象,介绍了雷达系统跟踪原理,跟踪问题的检查过程;然后,应用单脉冲跟踪原理分析问题产生的原因是和差数据不同步引起的,详细阐述了问题产生点的定位方法,确定问题是由于信号处理分系统数字信号处理加载时间不一致引起的,给出了跟踪问题的解决方法,并研究了针对此类问题的同步复位电路设计;最后,总结了雷达系统设计过程中应该注意的问题。

The phenomenon of radar＇s tracking problem is briefly stated, then the principle and the checking course of radar＇s tracking problem is introduced. The reason of the problem is non-synchronization of the sum and difference data. As a result of digital signal processing （DSP） loading disaccordly, the problem happened. The solution of radar＇s tracking problem and design of synchronization reset circuits is given. Finally the attentive problem in the radar system＇s design is summarizd.
