New scheme and circuit implementation of countering multiplesource high-repetition frequency laser jamming

多源激光高重频干扰和抗多源激光高重频干扰是激光对抗的重要形式,多源高重频干扰对抗中高重频信号识别和处理的难度更高。为此,提出了一种抗多源激光高重频干扰的新方案,该方案的核心是按制导信号周期进行延时后的信号与实时信号进行与操作。提出了多芯片使用同一振荡电路解决模拟实验中零漂问题的技术途径。得出了许多电路实验验证结果:制导信号和高重频干扰信号的复合模拟结果,多芯片使用同一振荡电路与不使用同一振荡电路的波门内信号的模拟结果,电路输出信号与输入制导信号的对比结果。结果表明:高重频干扰信号被高概率地滤除,电路输出信号为制导信号,抗多源激光高重频干扰新方案可行。该方案为激光对抗提供了一种新方法。

Multiple-source high-repetition frequency laser jamming and countering multiple-source high-repetition frequency laser jamming are important ways of laser countermeasures. It is more difficult to recognize and treat signals with high-repetition frequency for countering multiple-source high-repetition frequency laser jamming.Therefore a new scheme of countering multiple-source high-repetition frequency laser jamming was put forward. The core of scheme was the ＂and＂ operation was carried out between delayed signals in one guided periodand real time signals. A technical method of using the same oscillation circuit for multiple chips to solve zero-floating problem in simulational experiments, was proposed. Many circuit verification experimental results were obtained, such as compound signals of guided signal and high-repetition frequency signals, signals of wave gate with and without the same oscillation circuit in multiple chips, contrast of the output signal of circuit and the input guided signal. The results show that high-repetition frequency signals can be filtered on high probability, the output signal of circuit is guided signal, and the scheme of countering multiple-source high-repetition frequency laser jamming is feasible. The scheme provides a new method of laser countermeasures.
