讨论了一种先进的全固态、高速、高功率半导体开关DSRD的物理特性、工作原理、性能特点。利用DSRD的物理特性，提出了一种先进的超宽带雷达发射信号设计方法。利用该方法设计的超宽带雷达发射机具有高功率、高重频、体积小、重量轻、长寿命、高可靠等优点。

In this paper the physical property, working principle, and characteristics of an advanced solid-state, fast, high power switch are discussed. Exploiting the DSRD (Drift Step Recovery Device) characteristics, the design method of an advanced UWB radar transmission signal is proposed. The UWB radar transmitter designed in this way has the main advantages of high power, high repeating frequency, long life, very good stability (low jitter), small size, light weight and high reliability.
