摘　　要：动态范围是表示雷达接收机整体性能的一个重要指标,对测控雷达来说,其大小决定着雷达系统的测控距离和抗干扰能力。在对接收机及其数字化方式进行讲述的基础上,对C频段测控雷达接收机的动态范围的扩展方法进行了研究,分析了该类型接收机的基本原理,动态范围的含义,以及影响动态范围的因素,最后提出了扩展动态范围的几种方法。The dynamic range is an important indicator of the overall performance of the radar receiver, whose value determines the tracking and controlling distance and the anti-interference ability of the IT＆C radar. On the basis of the description of receiver and its digitization types, the dynamic range extension methods of a shipborne C-band TI＇＆C radar receiver were studied in this paper, the basic principle, the meaning of the dynamic range, as well as the effect factors of the dynamic range were analyzed, at last, the extension methods were put forward.
