为解决舰艇编队同型相参体制雷达间的同频干扰问题,文中针对相参体制雷达的主要特点,根据同频干扰的基本特 性,分析了相参体制雷达抗同频干扰的难点。采用时域多脉冲相关法抗同频干扰的基本思路,确立了相参雷达抗同频干 扰的技术指标,给出了抗同频干扰硬件设计,提出了抗同频干扰分机定时器模块、多脉冲相关模块、MTI模块和终端处理 模块的设计方法。该方法能够有效消除编队内同型号相参体制雷达之间的同频干扰。

Radar identical frequency jamming problem is an important problem restricting shipborne radars using. In order to solve the problem about identical frequency jamming between coherent-radars for the warship formation, aiming at the main characteristics of coherent-radars, difficulties of eliminate identical frequency jamming between shipborne coherent-radars are analyzed first. Then technical indexes are established based on correlation algorithm during multi-pulse in time domain. Finally a design method to eliminate identical frequency jamming between shipborne coherent-radars is proposed including timer modules, multi-pulse coherent module, MTI module and terminal handling module. Experiments on the sea show that this method can effectively eliminate identical frequency jamming between coherent-radars for the warship formation.
