现代航空技术的发展使低空防御更显重要

依靠雷达来搜索并发现来袭的低空目标是其中的首要关键。起这种作用的雷达目前主要有三种类型:地面（或舰载）低空搜索雷达、超视距雷达及机载预警雷达。前两类有其固有的弱点和缺点

因此八十年代的发展是以机载预警雷达为重点

其余只作为辅助用。本文就目前用于机载预警雷达的三种下视形式:低脉冲重复频率（LPRF）、中脉冲重复频率（MPRF）和高脉冲重复频率（HPRF）

论述了它们之间的区别

各需解决的关键技术及其难易程度

以及各所适应的地貌条件。结论是场合不同

其最佳的折衷选择亦将不同。

There are three different types of down-looking airborne early warning radar being used at present: low pulse repetition frequency radar

medium pulse repetition frequency radar and high pulse repetition frequency radar. Their differences

advantages and disadvantages

some of their technical problems to be solved

and the different ground features and clutters that they are designed for

are discussed. So the best trade-off solution can be made according to different situations and conditions.
