摘要
用于军事飞行模拟器训练的雷达成像,具有不受时间和空间的限制、可控、保密等特点,在模拟训练中起着重要的作用。本文概述机载火控雷达采用的RBM、DBS、AR这3种主要对地测绘方法,国内外战斗机雷达型号及其成像系统;总结国外雷达成像模拟软件及国内雷达仿真器研发的现状,对已有产品的优缺点、适用范围、所用技术做详细说明;介绍雷达成像模拟的主要方法及实现过程,将目前的雷达成像模拟方法划分为3大类:回波信号模拟、传递函数和雷达图像特征的融合;并预测雷达模拟仿真将向建立通用数据库、扩大成像范围、提高实时性和逼真度的方向发展。
Radar imaging for military flight simulator training plays an important role in simulation training because of its advantages of no limitation of time and space,controllability and strong security.In this paper,three main ground surrveying and mapping methods(RBM,DBS and SAR)for airborne fire control radar,domestic and foreign fighter radar models and their imaging systems are introduced.The research and development status of foreign radar imaging simulation software and domestic radar simulator are described.The advantages and disadvantages of existing products,their applicable scope and technologies are described in detail.The main methods and realization process of radar image simulation are summarized,which are divided into three categories:echo signal simulation,transfer function and fusion of radar image features.It is predicted that radar imaging simulation will develop in the direction of establishing general database,expanding imaging range,and improving real-time performance and fidelity.
