Abstract :
Pulse compression using a digital-analog hybrid technique is studied to achieve very low range sidelobes for potential application to spaceborne rain radar. Range sidelobe suppression of 60 dB is attained in both calculation and test measurement by optimizing the transmission signal to cancel the defects in pulse compression process
