引言雷达设计师必须作出选择的最重要参数之一就是波形。早期的雷达研制工作部集中在低脉冲重复频率波形的设计方面。后来,重点就转移到相干的高脉冲重复频率波形的设计,特别是采用下视工作方式的空-空搜索情况,这是本文最关心的问题。由于需要对抗地物杂波和提供下视能力,更加速这种转移。因此,对中脉冲重复频率领域的研究是自然的发展趋势。 Introduction One of the most important parameters that radar designers have to make is waveform. Earlier radar research work focused on the design of low-pulse repetition frequency waveforms. Later, the emphasis shifted to the design of coherent high-pulse repetition frequency waveforms, especially the air-to-sky search using the down-view mode of operation, which is the most concerned issue in this paper. This transfer is accelerated by the need to combat clutter and provide the ability to look down upon. Therefore, the research on the field of medium pulse repetition frequency is a natural trend.
