Abstract:
In view of the characteristics of a high-frequency ground wave radar,the ambiguity function of frequency modulated interrupted continuous wave(FMICW)signal is derived based on the principle of ambiguity function.Range resolution and Doppler resolution which influence monostatic FMICW radar signal are analyzed.Furthermore,the ambiguity function of bistatic or multistatic FMICW radar signals is concerned with the bistatic angle.When the target is in the vicinity of the baseline,the shape of ambiguity function is stretched and the target resolution is evidently degraded.Mathematical analysis and simulation results show that the resolution is related to the FMICW signal form and affected by the target position.The target resolution of the FMICW radar signal is higher when more transmitters and receivers are properly used.
