Anti-jamming Filtering for DRFM Repeat Jammer Based on Stretch Processing
This paper addresses issues about the rejection of false jammer targets in the presence of digital radio frequency memory (DRFM) repeat jammer. An anti-jamming filtering technique is proposed that it can eliminate this type of jam ming signal. By using a stretch processing with a particular selected reference signal, the presented method can fully separate the echoes being reflected from the true targets and the signals being re-transmitted by a jammer in frequency domain. Therefore, utilizing the nonoverlapping properties of the received signals, filters or sucblike techniques can be used to reject the undesired jamming signals. Particularly, this method does not require estimation of jamming signal parameters and does not involve a great computation burden. Simulations are given to sbow the validity of the introduced approach.
