基于多波束雷达测高的地形高度匹配算法研究
The Terrain Elevation Matching Algorithm Based on Mul ti-Beam Radar Height Measurement
摘要
Abstract
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 .关键词
