摘　　要：如何科学、客观地衡量雷达抗干扰能力,不仅是新型雷达装备设计改进的前提,更是雷达日常运用、维修保障、电子战仿真分析的重要保证。该文针对目前雷达抗干扰性能测试指标种类繁多、外场测试条件难以控制且代价高昂等问题,选取了合适的抗干扰性能指标模型,设计了基于开放空间的半实物辐射式指标测试仿真实验方案。通过雷达仿真模型与硬件设备相结合,利用火控雷达抗有源干扰性能测试信号源,构建了一套逼真的雷达抗干扰仿真测试系统来获取大量的实验数据,提高了对雷达系统抗干扰能力的分析与测试水平,提升了日常训练水平和保障能力,对雷达装备研制和作战效能评估具有一定指导意义。[Objective]Radar anti-jamming performance evaluation is a scientific method to assess a radar’s ability to resist interference.It is a prerequisite for the design and improvement of new radar equipment and serves as an important guarantee for daily operations,maintenance,and training.However,the complexity of radar electronic warfare and the diversity of radar interference and anti-interference technologies present significant challenges.These include numerous types of testing indicators,poor universality of testing methods,difficulty in controlling field testing conditions,and high costs.These factors make it challenging to compare radar anti-interference performance test results and prevent the formation of reliable,conclusive opinions.[Methods]A method for evaluating radar anti-interference performance based on semi-physical simulation experiments is proposed.The approach includes a testing scheme using open-space semi-physical radiation simulation experiments,providing new ideas for integrating in-field and out-field experiments in electronic warfare shooting ranges.This approach enriches the experimental evaluation mode.Fire control radar is the primary focus of this study.After a thorough analysis of existing radar anti-interference performance testing methods and indicators,representative and measurable anti-interference performance testing indicators were selected.A semi-physical simulation test plan was then developed,utilizing a radar anti-interference test signal source.This source generated RF signals containing target echoes and interference signals.The performance of the radar receiver was assessed under various conditions,including RF noise,noise amplitude modulation,and noise frequency modulation interference.The corresponding radar anti-interference indicators were calculated through data acquisition.By comparing and analyzing changes in these indicators in different battlefield environments,the study provides valuable data to support radar anti-interference testing and evaluation performance.I
