  • Since the sidelobe suppression of a random signal is a difficulty in research, it has realistic meaning to suppress the sidelobe in a simple and effective way. A continuous time model of random frequency modulation signal is developed in this paper. The root mean square bandwidth and point spread function of the random frequency modulation signal both in gaussian and uniform distribution cases are investigated theoretically. The signal model is verified by the result of the simulation, which shows that it can obtain a higher Peak SideLobe Ratio(PSLR) that the linear frequency modulation case, and it can achieve a good effectersult in radar imaging.
