摘要
A novel digital radio frequency memory (DRFM) system used in repeater radar jammer was proposed. The principle of filter bank and the common structure of DRFM system were introduced. Considering the analysis and synthesis ability of filter bank, DRFM system based on filter bank was derived and designed. The proposed DRFM system has the advantages of broad band coverage and wide dynamic range. It also can realize perfectly the reconstruction of cross-channel signal in channelized reception. The repeater radar jammer with DRFM system have already been tested, which proved the property of this system.
