摘　　要：目前舰载雷达主要采用捷变频、复杂重频、宽带高增益脉冲压缩、低副瓣天线以及发射功率管控等低截获概率设计技术来提高其反电子侦察和抗干扰能力,属于"防御性"的反电子侦察技术。从电子侦察系统的特点及存在的弱点出发,提出对其进行干扰的可能性,采取主动反电子侦察的方法来掩护己方舰载雷达工作,提高舰载雷达的电子对抗能力。The low probability of intercept（LPI）techniques,belonging to ‘defence＇counter electronic support measure（CESM）technology,such as frequency agility,complex PRF,broadband high-gain pulse compression,low side-lobe antenna and flexible beam control technique,are used to improve the CESM ability and anti-jamming ability of shipborne radar.According to the characteristics of electronic reconnaissance system,and the probability of being jammed,active CESM techniques are proposed to cooperate with the shipborne radar and improve its electronic countermeasures ability.
