摘要

为了降低野外对空中观测实验的复杂度和成本，设计了基于VGA接口液晶显示屏的通用空中目标室内模拟仿真平台，并对该平台所采用的基于空间位置/大气密度的空中目标形态/能量实时更新模拟算法进行研究。平台由S3C2440处理器和VGA接口组成，在每一时刻计算模拟目标的瞬时高度、距离、速度，结合这些参数并依据大气密度变化和能量制约算法，实时生成模拟目标的显示位置和尺寸大小，并通过VGA接口把模拟目标显示在液晶屏上。测试结果表明，利用该平台对空中的目标模拟，与传统的野外实测相比降低了90%以上的成本，且具有可随意变更观察目标和实验重复性好的优点，能满足在单一背景下模拟空中目标的需要。

Abstract

In order to reduce the complexity and cost of optical observation system for air

a general purpose emulation system is designed and produced based on liquid crystal(LC) screen with VGA port to simulate the space objects in lab. In addition

this paper investigated the algorithm of real-time updated object's shape and energy based on its space position and atmospheric density used in the system.The system is composed of S3C2440 processor and VGA port. At every moment

it calculated the object's parameters including height

distance and velocity. With these parameters

it calculates the object's position and size on screen in real time according to atmospheric density variation and energy limitation. Finally

the emulated object is displayed on the LC screen through VGA port. The experimental results indicate that the experimental cost with our system is decreased by 90% than those in field. In addition

the system has the advantages of randomly change and good repeatability. It can emulate different space objects in a single background.
