摘　　要：杂波模拟是雷达数字化设计与仿真的基本功能之一,杂波模拟需要解决杂波模型与雷达模型的接口和杂波模型的设计与实现两大问题,以确保雷达杂波模拟的可用性和真实性。为此,针对雷达数字化设计与仿真技术中杂波模拟问题,提出了杂波模型与雷达模型接口参数的统一描述方法,并分别给出了面杂波和体杂波的具体设计与实现方法,重点针对陆、海及箔条杂波给出了其RCS计算步骤和方法,最后仿真验证了杂波模拟方法的有效性和可用性。Clutter simulation is one of the basic functions of digital radar design and simulation.To guarantee the usability and fidelity of simulated clutter,two technical challenges must be addressed,namely the interface between clutter model and radar model and the design and implementation of a clutter model.This paper proposes a unified interface parameter description approach and design and implementation approaches of surface clutter and body clutter.In addition,the RCS computation of ground,sea,and chaff clutter are explained in detail.The simulation results show the feasibility and effectiveness of the proposed clutter simulation approach.
