一种模拟干扰下的雷达模拟目标实现方法
|
摘要
介绍了一种可接入干扰背景的雷达目标模拟的实现方法。计算机控制下,采用控制波门电路控制DDS(直接数字频率合成器)产生模拟信号,实现了具有多普勒频移、高度信息的模拟目标的生成。模拟的干扰信号构成了模拟目标的干扰背景。采用此系统可以对雷达系统进行准确的功能检测和性能测试。该方案已应用于实际雷达系统的测试,验证了设计的正确性和有效性。
The implementation method of radar simulative target in jamming background is introduced. By computer controlling,the circuit of control gate is adopted to control DDS to produce analog signals. It can generate simulative targets which have Doppler Shift Information and height information. The simulative jamming signals constitute the jamming background of radar simulative target. This design can achieve an accurate function detection and performance test of the radar system.The whole system has been successfully implemented in the practical radar platform,and the correctness and validity are also proved.
