近几年来地形辅助导航系统（TAN）受到广泛重视并已成功应用。该系统的核心之一是地形高度匹配算法（TEM ）。本文在分析单波束雷达测高互相关匹配算法（COR）的基础上，提出一种基于多波束雷达测高的互相关匹配算法，该算法将一维COR匹配算法扩展到二维中，并建立相关模型，利用二维COR匹配算法搜索计算飞行器位置。导航仿真结果表明：该算法的匹配精度、地形适应性都要优于一维COR匹配算法。

In recent years ,Terrain‐Aided Navigation (TAN) system was emphasized ex‐tensively and has been successfully applied .One of the core of the system is Terrain Eleva‐tion Matching algorithm (TEM) .This paper analyzes the single‐beam radar height measure‐ment COR matching algorithm (COR‐CrossCorrelation ,COR) ,and proposes a new COR matching Algorithm based on multibeam radar height measurement .The algorithm will be extended one‐dimensional COR matching algorithm to two dimensions ,and established the relevant model .Navigation Simulation results show that the accuracy and terrain adaptability of the new matching algorithm is better than one‐dimensional COR matching algorithm .
