713雷达回波信号实时数字处理系统的硬件接口

THE INTERFACE OF THE REAL-TIME DIGITAL EcHo PROCESSING SYSTEM IN MODEL-713 RADAR

本文介绍的接口电路是为《713雷达回波信号实时数字处理系统》设计的。接口电路包括雷达触发脉冲、天线方位零度和仰角零度信号的波形与幅度变换电路以及雷达接收机输出的回波视频信号的幅度放大与底部钳位电平的平移电路。目的是通过它们向后级电路提供合适的输入信号。

The interface circuit presented in this paper is designed for the real-time echo processing system in Model-713 radar. The circuit is composed waveform and amplitude transforming circuit of triggering pulse and antenna 0° of azimuth-elevation,amplitude amplification of echo video signals from the receiver and translating circuit at the base level,through which suitable signals are supplied for the successor circuits.
