雷达景像匹配制导基准图制备技术综述

Reference map generation techniques for radar scene matching guidance: an overview

基准图制备是雷达景像匹配制导的一项关键技术,其中制备方法的选择决定了景像匹配制导系统的总体性能。详细综述了目前雷达景像匹配制导基准图制备的研究现状、存在问题及研究展望。目前,人们主要从特征模拟及信号模拟两方面模拟雷达图像来制备基准图,还没有一种制备技术能完全满足雷达景像匹配制导的要求,各种技术都存在各自的优缺点和适用范围。制备基准图参考源的挖掘、基准图分辨率的提高、寻的目标模板的有效生成等依然是目前和今后一段时间内雷达景像匹配制导基准图制备的主要研究问题。

Reference map generation is a key to the radar scene matching guidance. The selection of generation methods determines the overall performance of a radar scene matching guidance system greatly. This paper presents an overview of the progress made in the field of the reference map generation technique for radar scene matching guidance, analyses the existing problem, and prospects for the developing trends. The reference map is generated by two main techniques at present： one is characteristic simulation, and the other is signal simulation. But neither satisfies the requirement of the radar scene matching guidance completely. In particular guidance applications, each works with its advantages and disadvantages. At present the main issues of the reference map generation for radar scene matching are discovering more reference sources, improving distinguishing ability, and generating the homing target templates effectively.
