某型机载雷达信号发生器功能扩充方法研究

Study of Expanding Function Method for Airborne Radar Signal Generator

针对某型机载雷达信号发生器信号样式单一、载波频点对应的脉冲宽度和重复周期值较为有限的问题,利用CPLD技术重新制作信号发生器的信号调制板,增加了脉冲宽度值、重复周期值和一种抗干扰信号样式--重频参差,扩充了信号发生器的功能,最后给出仿真结果与硬件测试结果。

In allusion to the limitation that signal mode and quantities of PRI values and PD values in the Airborne Radar Signal Generator are lack, a new PCB is rebuilt based On CPLD （Complex Programmable Logic Device） technique, which can modulate signals. It gener- ates more quantities of PRI values and PD values. By the way, a kind of ECCM signal mode--Staggered PRF was added. At last, the result of simulation and experimental test are given.
