| Abstract: | Time - frequency analysis can improve the performance of space - time adaptive processing for non - stationary interference. A space - time - frequency adaptive processing anti - jamming algorithm for CPS application is presented. The algorithm suppresses most types of interference from different incidence angles in space domain, and also suppresses non - stationary interference such as sweep jammer according to spectrogram in time - frequency domain. Simulation results prove the validity of the algorithm. |
