Radar echo simulation method with variable number of scattering points

The invention discloses a variable-number scattering point radar echo simulation method, which is characterized in that a complex false target is decomposed into a plurality of number of scattering points based on a radar signal echo model of a geometric diffraction scattering center theory, and each scattering point has own scattering characteristics, mainly including four characteristics of distance, speed, phase and amplitude; and then performing hierarchical simulation on the four characteristics to finally obtain variable-number scattering point signals, performing signal combination processing, and simulating a false target echo simulation signal which is highly similar to a real radar target signal and has strong interference capability. 本发明公开了一种可变数量散射点雷达回波模拟方法，基于几何绕射散射中心理论的雷达信号回波模型，将一个复杂的假目标分解为多个数量散射点组成，每个散射点都有自己的散射特性，主要包括距离、速度、相位以及幅度四个特性；然后对四个特性分级模拟，最终得到可变数量散射点信号并进行信号的合并处理，模拟出与真实雷达目标信号高度相似，且具有强干扰能力的假目标回波模拟信号。
