| 摘 要： | 雷达工作于脉冲工作状态时不可避免的会出现盲速现象。可通过参差重频的方法减少盲速带来的影响。在推导频率响应的基础上,该文采用最优化设计的方法进行参差周期的设计,详细考虑并推导得到了最优化搜索中几个重要参数,给出了其解析表达式。仿真结果和频率响应图表明,该方法得到的参差周期能将慢速扩大到原来盲速的数倍以上,有效地减少了盲速的影响。

| Abstract: | When radar operates on pulse state, it will inevitably encounter the phenomenon of blind speed. The staggered pulse repetition frequency(PRF) is one of the most important methods to suppressing the blind speed. Based on the derivation of frequency response, this paper proposes a method of optimum design for staggered periods, among which the considerations and derivation for several essential parameters of optimal search are also given out in detail. The simulation results and the frequency response figures... |
