提高对雷达隐蔽扫描角跟踪系统干扰性能的研究

Research on Raising the Countermeasures Performance to the Concealing Scanning Radar Angular Following System

分析了对隐蔽扫描雷达角跟踪系统实施匀速扫频式干扰的缺点,提出了一种实现快速-慢速扫频的方法,即先快速扫描以捕捉雷达角扫描频率范围,再在此小范围内进行慢扫,以确定敌方雷达的角扫描频率。文中还给出了改进的系统结构和主要电路框图,并结合该系统的改进内容针对研究中的主要技术难点作了详细的分析。

After simply analyzing the deficiencies in countermeasures to the concealing scanning radar angular following system, a new method is presented which means scanning slowly in a smaller range after quickly scanning to get the precise sweep frequency. The block diagrams of system composition and improved primary electric circuits are also given. Finally, the main technical difficulty on system improvement is analyzed in detail.
