一种相控阵雷达新型搜索波形研究

摘要

To solve the problem that the conventional phased array radar waveform takes relative large amount of resources of time,we studied the working mode of phased array radar and the traditional timeshare transmitted pulses with different repetition periods .Based on which,a search method was proposed based on a novel three-band search waveform,the parameter selecting principles and signal forms in time domain and frequency domain were given .The analysis to an example shows that this kind of signal can effectively save the time and improve the search performance .Finally,some of the outstanding issues are discussed .%针对传统相控阵雷达搜索波形占用时间资源较大的问题，在充分研究相控阵雷达工作方式以及具体分析传统分时发射不同重复周期脉冲的搜索方式基础上，提出了一种新型的三频段搜索波形，并给出了其参数选择原则和信号的时域频域形式。经实例分析，证明这种信号可以有效节省搜索占用的时间资源，并提高搜索性能。最后对一些尚待解决的问题进行了讨论。
