摘要
电磁对抗在现代战争中发挥着越来越重要的作用,雷达对电磁干扰的抑制能力决定了雷达能否发挥作战能力.本文重点研究近主瓣干扰的识别与抑制,给出了 一种雷达近主瓣干扰的识别方法,提出了一种基于双差通道的近主瓣干扰抑制方法,并分析了应用该方法进行干扰抑制后对雷达测角能力的影响.仿真结果表明,本文所提方法能够抑制来自波束近主瓣的干扰,并且具备一定的工程实用性.
Abstract
Electromagnetic countermeasures play an increasingly important role in modern warfare.A radar's ability to suppress electromagnetic jamming determines whether it can exert its combat capabilities.This paper focuses on the identification and suppression of radar near-mainlobe jamming.First,a method for identifying near-mainlobe jamming is provided.Then,a near-mainlobe jamming suppression method is proposed based on double difference beam.Finally,the influence of the proposed suppression method on the angle measurement capability of the radar is analyzed.The simulation results show that the proposed method can suppress the jamming from near-mainlobe of the radar beam.It has certain engineering application value.
