摘要
脉冲压缩雷达有效解决了雷达作用距离与距离分辨率之间的矛盾,其多变的脉内调频技术使其低截获概率成为可能。脉冲压缩技术在雷达设计中的广泛应用,对雷达对抗系统的设计提出了新的挑战。介绍了脉冲压缩雷达的工作原理,阐述了雷达对抗系统对其侦收、分选、识别和干扰的技术途径及其实施方法。
Pulse compression radar can effectively resolve the contradiction between radar operational range and range resolution, and the changeful intra-pulse frequency modulation technology makes the low intercept probability possible. Pulse compression technology has been used in the radar design widely, which brings forward new challenge for the design of radar countermeasure system. This paper introduces the operating theory of pulse compression radar, expatiates technical approaches and implementing methods that the radar countermeasure system performs reconnaissance, reception, identification and jamming.
