一种多功能雷达中频模拟器设计及实现

Design and Implementation of a Multi-functional Radar Intermediate Frequency Simulator

雷达信号的数字化仿真与评估技术在雷达系统的设计过程中具有重要地位，文中论述了一种多功能雷达中频模拟器的设计及实现方法，该系统采用了直接数字合成（DDS）雷达信号产生技术，并通过模拟雷达单脉冲天线和、方位差、俯仰差的方式进行雷达回波信号、杂波信号的模拟，进行雷达运行过程的仿真，用于模拟雷达调试、性能评估和算法验证。

The digital simulation and evaluation of radar signal plays an important role in the design of radar system. This paper de- scribes the design and implementation of a multi-functional radar intermediate frequency （IF） simulator. The system uses the DDS radar signal generation technology. Echo and clutter signals are simulated by simulating the radar monopulse antenna＇s sum, azi- muth delta and elevation delta, the simulation of radar operation is carried out. It uses for the simulation of radar testing, perform- ance evaluation and algorithm verification.
