| Abstract: | A novel idea of orthogonal frequency division multiplexing (OFDM) fuze system is proposed. In the system, it detects the target with many parallel different channels at the same time and the information of range and velocity between fuze and target is achieved from the time-frequency correlation of the returned signal. The performance of anti-jamming and range finding is primarily analyzed and it shows that the performance of anti-jamming and the precision of information are high. |
