| Abstract: | Aimed at anti-communication interference to radar, applying the time-frequency analysis scheme to suppressing communication interference, in which the ratio of bandwidth from the radar main lobe to the total signal bandwidth is greater, was proposed and analyzed, based on the method of time-frequency projection filter. Used LMF and MSK signals as the objects and simulated by computers, the simulation result proves that the scheme is feasible. |
