A Radar and Jammer Simulation Method Using Signal Descriptor

针对多对多的雷达与雷达对抗信号级仿真系统难以扩展的问题,实现了一种基于信号描述字的雷达与干扰仿真方法。首先,分析了相参脉冲串目标回波数字仿真理论与方法;以此为基础,对数字信号的仿真过程进行拆分,提炼了信号描述字的组成要素;然后凝练得到5类信号描述字,并讨论了信号描述字如何适应信号样式多样性的问题;最后,通过两部雷达和两部干扰机的对抗仿真实例,验证了方法的有效性和对于多对多雷达对抗信号级仿真的适应性。

In many-to-many radar countermeasure signal-level simulation system,the close coupling between the radars and the jammers often results in poor extensibility.A signal descriptor method is proposed to solve the problem.Firstly,the theory and method of digital simulation of coherent pulse train target echo are analyzed.On this basis,the simulation process of digital signal is decomposed,the components of signal descriptors are extracted,and then five kinds of signal descriptors are obtained,and how the signal descriptors adapt to the diversity of signal styles is discussed.Finally,the effectiveness of the method and its adaptability to many-to-many radar countermeasure signal-level simulation are verified via the simulation examples with two radars and two jammers.
