Abstract :
Signal generator is an important part for a Radar system. In this paper, the Pre-distortion for baseband signals and intermediate frequency (IF) signal is introduced. The signal generator with the effective pre-distorition methods in time and frequency domain based on DDWS is realized. Experimental results of the signal generator are presented, which prove the pre-distortion are reasonable and effective. Temperature and vibration tests are also involved to validate the stability and reliability.
