Research on Forward-looking Ranging Algorithm of Missile-borne Phased Array Detector Based on Pulse Compression

Abstract

Aiming at the forward-looking ranging problem of phased array detectors, this paper proposes a forward-looking ranging algorithm suitable for missile-borne phased array detectors, it uses stepped pulse compression to extract the distance information from the echo signal, and it achieves high-precision and high-efficiency distance the target area for a missile-borne platform with high real-time requirements. In this paper, the forward-looking ranging model of the missile-borne detector is established, and the linear frequency modulation sub-pulse frequency stepping signal system is used as the ranging signal. Then the ranging principle of the missile-borne detector is derived from the ranging theory. Finally, the ranging algorithm was verified through simulation experiments.
