Abstract: Aiming at the problem of modulation that there is no actual radar in the process of analyzing the signal quality of the intermittent irradiation radar,this paper puts forward a method of simulating radar waveform with arbitrary waveform generator and microwave signal source according to the principle of generating complex intermittent irradiation radar signal.Based on software radio technology,it gives a concrete implementation plan of simulating complex baseband modulated signal with MATLAB software and importing it into arbitrary waveform generator.By adopting the signal simulation method designed by the scheme,the generated signal covers rich contents such as modulation subcarrier parameters,pulse synchronization signals,coding information and so on.It can solve the problem of acquiring complex intermittent illumination radar signals in a laboratory environment.The experimental results show the simulation signal scheme has the characteristics of good universality and is easy to implement,which can provide methods for complex modulation signals generating in the same signal system,and reduce the test cost.
