| Abstract: | This paper analyzes the performance of the pseudo-random code continuous wave（PRC-CW） radar,researches the operation theory of PRC-CW radar,emphatically deduces the ambiguity function of PRC-CW radar,simulates the radar signal by computer,by comparing the simulation diagrams between 13-bit Barker code phase modulation signal and 63-bit m sequence phase modulation signal,proves out that the long code modulation signal simulation diagram is the best selection for PRC-CW radars,and in order to realize the better range measurement and speed measurement,the side-lobe restrain circuit has to be added or the better code be selected. |
