| 摘 要： | 针对地形匹配脉冲雷达高度表的应用特点，提出基于M-OCOG算法的数宁式回波搜索跟踪器。分析了回波截获概率和跟踪性能，并通过对实际采集回波数据的连续仿真来展示该搜索跟踪器的地形匹配效果。结果表明，M—OCOG搜索跟踪器即使是在低信噪比时仍可保持高的回波截获概率，极强的网波跟踪鲁棒性以及在各高程范围良好的测高精度与地形匹配效果，为其工程应用奠定了基础。

| Abstract: | A novel digitalized searehing-tracking scheme based on the M-OCOG algorithm is firstly presented for intproving the total performance of the TERCOM pulse radar altimeter in the paper. The echo - acquisition probability and traeking performance are analyzed anti the terrain contour matching performance is shown and compared with that of the normal OCOG tracker by using real sampling echoes. The analysis resnhs show the acquisition probability is still high even low echo-SNR. The performances of robust echo-traeking ability, good height-measnring preeision and terrain contour match effect for different height ranges manifest the engineering applieution potential of the M-OCOG searcher-traeker. |
