%X In according with the difference of the CS imaging processing algorithm and the RD imaging processing algorithm, the signal and the jamming imaging processing gain of the two algorithms is analyzed at the environment of noise jamming. And the formula of the signal-to-jam ratio (SJR) processing gain is deduced and analyzed. The analyzing result demonstrates that the SJR processing gains of the RD and CS imaging algorithm are uniform at the condition of the sampling rate is only larger a little than the band width of the signal. And at the condition of the over sampling rate, the SJR processing gain using RD algorithm is larger than using CS algorithm due to the two dimension matching filter of RD algorithm. However, if the over sampling signal is filtered, the SJR processing gain of CS algorithm is uniform with the RD algorithm. The computer simulation testifies the validity and the availability of the conclusion.
