摘要

Combined sky-wave and surface-wave monostatic high-frequency (CSSM-HF) radar is a new type of mono-static high frequency (HF) radar that uses multiple combined propagation modes of skywave and surface wave to detect targets. However, the detection range of different propagation modes partially overlaps, which results in multiple mode echoes from one target. To track the target in the presence of multi-mode echoes, a new multi-mode target tracking algorithm is proposed in the study, which uses the detection range as a priori knowledge. In CSSM-HF radar, the possible propagation mode of the target echo is related to the position of the target itself. Therefore, the study uses the detection range simulation results as a priori knowledge to construct a propagation mode judgment module to effectively improve the calculation efficiency and performance of the tracking algorithm. The simulation results show that the proposed algorithm can effectively track the target in the presence of multi-mode echoes and the tracking performance of the target with lower abscissa speed is better. In addition, the mode judgment module directly affects the performance of the algorithm. The tracking performance will be reduced when the output of the mode judgment module has an error mode.
