Abstract: 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. -
