Abstract :
The transmit signal and receive signal model of orthogonal FDLFM radar is constructed in this paper, the ambiguity function of narrowband FDLFM radar is derived based on the theory of narrowband ambiguity function. Besides they are simplified by the orthogonal characteristics between the transmit signals of narrowband FDLFM radar, we can get the conclusion that the range resolution is decided by the bandwidth of the transmit signal and the bandwidth among the transmit signal simultaneously. The characteristics of AF and the range resolution of FDLFM signal are simulated and analyzed, and the matched filtering and pulse accumulation of FDLFM signals are simulated and analyzed.
