多径效应的存在导致雷达跟踪低角目标时性能下降甚至失效,研究抑制多径效应的阵列雷达低角跟踪技术对于应对低空、超低空突防威胁具有重要意义。在对多径效应的成因和影响进行分析的基础上,简要介绍了典型阵列雷达在低空探测中的优势与不足,分析研究了具有代表性的阵列雷达低角跟踪技术,最后对阵列雷达低角跟踪技术未来的研究方向进行了展望。
The existence of multipath effects leads to the performance degradation or even failure of the radar when tracking low-angle targets. Studying the low-angle tracking technology of array radar with suppression of multipath effects is of great significance to deal with the threat of low-altitude and low-altitude penetration. Based on the analysis of the causes and effects of multipath effects, the advantages and disadvantages of typical array radar in low altitude exploration are briefly introduced. The representative low-angle tracking technology of array radar is analyzed. Finally, The future research direction of tracking technology is prospected.
