摘要
在电子对抗条件下,如何在密集的电磁环境中实时地分离出各雷达辐射源信息、得到正确的测量参数是进行雷达干扰的关键。简要介绍了雷达脉冲参数包括载频、脉冲宽度、脉冲重复周期、脉冲幅度和脉内调制参数的测量方法和通过序列差值直方图算法进行雷达信号分选的原理,给出了在电子侦察系统中采用软件无线电技术,通过DSP完成雷达脉冲参数测量与分选的设计方案和工程实现。
How to separate the radar radiating points in real time in the dense electromagnetic environment and get the correct measurement result is the key of the radar jamming. In this paper, the measurement methods of the pulse modulated signals parameters such as frequency, pulse width, pulse repetition interval, pulse amplitude and the modulation parameter inside pulses, and the resolution principles of radar signals by sequential difference histogram. For the electronic reconnaissance system, the design methods of the parameter measurement and signal resolution by DSP which use the software wireless and the digital down frequency conversion in radar pulse modulated signals are presented. The method can he used in practical projects.
