摘　　要：针对干扰性能评估方法和指标复杂多样、评估准确性不足的问题,提出了基于等效雷达散射截面(Radar Cross Section,RCS)的有源干扰性能评估方法。该方法通过分析雷达受干扰部分的功率实现对干扰性能的评估,包含了干扰、雷达以及传播等多个环节的影响因素,最终以等效RCS作为参数对干扰性能进行量化评估。结合对压制式干扰的理论分析,通过在外场利用RCS测量雷达对多种干扰样式进行干扰性能测量实验和验证,表明该方法能够以较高的精度实现干扰性能的量化与评估。Jamming performance evaluation methods and indicators are complex and diverse,and the evaluation accuracy is insufficient.An active jamming performance evaluation method based on equivalent radar cross section(RCS)is proposed.The jamming performance is evaluated by analyzing the power of the jamming part of the radar.The influence factors of jamming,radar and propagation are included.The equivalent RCS is used as a parameter to quantitatively evaluate the jamming performance.Combined with the theoretical analysis of the suppression jamming,the jamming performance measurement experiment and verification of various jamming modes by using RCS measurement radar show that this method can realize the quantification and evaluation of jamming performance with high accuracy.
