摘要
该文给出一种调频中断连续波(FMICW)高频地波海况监测雷达的仿真模拟检验系统。该系统基于FMICW高频地波雷达的工作机理,以及一阶和二阶Bragg-Doppler谱的反演原理,利用直接数字合成的技术仿真出海洋雷达回波的模拟信号,以供雷达的校准与定标之用.该系统已与FMICW高频地波雷达测海系统进行了联机测试,得到了预期的效果。
An ocean echo signal simulation system for verification and calibration of FMICW high frequency ground wave radar is presented in this paper. It is based on the principle of FMICW radar and inversion of Bragg-Doppler(B-D) spectrum. The ocean echo signals are simulated with the digital synthesis techniques. They are used for calibration of the sea-state ocean radar. The system has been tested on an FMICW radar system, the surveillance results are favorably anticipated.
