Abstract :
If the mirror Doppler frequency components not be suppressed well in airborne pulsed Doppler radar, which would bring on false target detection, how to suppress the mirror Doppler frequency is an important issue to enhance radar performance. This paper proposed an method for the suppression of mirror Doppler frequency based on Hilbert transform, the results of processing experiment data show the suppression degree improved about 4 dB more than conventional methods
