| 摘 要： | 1 .INTRODUCTIONWith the rapid development of radar technology ,The technology of high-resolution radar i mage for-mationis gradually getting mature , and the coun-termeasure to high-resolution radar is growing a re-search hot point in the field of ECM. In order toattain high-resolution, High-resolutionradar usual-ly adopts the wideband pulse signal with 1 GHzbandwidth and over . So the realization of A/D( Analog/Digital) conversionis more difficult in en-gineering practice . For the s…

| Abstract: | The principle of uniform DFT filter bank is presented. Exploiting poly-phase structure, radar jamming system samples the intercepted wideband radar signals through analysis filter bank by different channels and linearly modulates the intercepted radar signal according to the theory of signal and system, then synthesizes the jamming signal through the synthesis filter bank. The method merely requires lower sample frequency, reduces the computational complexity and the data quantity to be processed. The un-ideal filter's influence to the result of signals processing is analyzed by simulating the match filter in radar jamming system. |
