摘要
在分析多径效应形成原理的基础上,论述了低仰角跟踪时多径效应对跟踪系统的影响。对基于多信息源的目标测量模型建模、数据融合与最优估计算法等解决低仰角跟踪的措施进行了研究。利用这些措施可有效改善无线电测量设备低仰角跟踪稳定性,并提高测量设备跟踪低空目标时的测量精度。
Based on the analysis of the principle of multipath effect, the influence of multipath effect on low angle tracking system is elaborated in this paper. Target measurement modeling based on multi-information source, data fusion and optimal estimation algorithm are effective measures to perform the low-angle tracking and are studied in detail, which improve the low angle tracking stability of radio measuring equipment, and increase the measurement precision of low-altitude target tracking.
