新一代数字储频中两种新技术的应用

The application of two kinds of new technologies in the new-generation digital frequency memories

数字储频设备是一种射频信号转发装置,接收雷达辐射信号,通过对信号的多普勒调制和距离延迟,产生相对于雷达站的目标回波信号,作为雷达标定和性能测试所需的目标信号。本文研究了自适应门限和多目标生成两项关键技术,对提高数字储频设备的工程实用性具有重大意义。

The digital radio frequency memory is the repeating equipment for RF signals. It receives signals radiated by radars, and generates, through the Doppler modulation and range delay, the target echoes relative to the radar station and makes the echoes as the target signals necessary for radar cali-bration and performance test. The key technologies as adaptive threshold and multi-target generation are studied, which are of great significance for improving the engineering practicability of digital frequency memories.
