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.

天波和面波单静态高频雷达的多模式目标跟踪

天波和面波组合式单静高频（CSSM-HF）雷达是一种新型的单静高频（HF）雷达，它使用天波和面波的多种组合传播模式来检测目标。但是，不同传播模式的检测范围部分重叠，从而导致来自一个目标的多个模式回波。为了在存在多模回波的情况下跟踪目标，研究中提出了一种新的多模目标跟踪算法，该算法将检测范围作为先验知识。在CSSM-HF雷达中，目标回波的可能传播模式与目标本身的位置有关。因此，该研究以检测范围模拟结果为先验知识，构建了传播模式判断模块，有效提高了跟踪算法的计算效率和性能。仿真结果表明，该算法在存在多模回波的情况下可以有效地跟踪目标，横坐标速度较低的目标跟踪性能更好。另外，模式判断模块直接影响算法的性能。当模式判断模块的输出为错误模式时，跟踪性能将会降低。模式判断模块直接影响算法的性能。当模式判断模块的输出为错误模式时，跟踪性能会降低。模式判断模块直接影响算法的性能。当模式判断模块的输出为错误模式时，跟踪性能会降低。
