| Abstract: | It is one of the development directions of passive radar to expand the number of illuminators and increase the available signal power to improve the system performance.Aimed at the FM broadcasting passive radar,this paper researched the coherent processing technique based on multi-frequency signals.Starting from signal model,it deduced the expression of each matching-filter output,and analyzed the phase relationship of each signal and various factors infecting coherent integration of multi-signals.The differentia phase item of each signal was compensated during signal processing to realize coherent integration.At last,the performance improvements of range distinguishing,clutter restraint and detection SNR were discussed.Simulation results proved the valid of the theory analysis,and it was important to improve the system performance of passive radar. |
