Abstract :
Digital radio frequency memory (DRFM) is an advanced electronic countermeasures tool in electronic warefare systems. The authors address the inherent problem of spurious signals in DRFMS and present an idea based on intentional time jitter which is applied during the sampling process to reduce the spurious signals level.
