基于STK与Matlab相结合的卫星对目标的可见性分析

Visibility analysis of satellite to target based on STK and Matlab

卫星仿真工具包能够准确计算出特定目标与其他相关对象的空间关系,以仿真时间或真实时间精确显示并分析陆、海、空、天目标,也可实现卫星以及其他载荷的覆盖分析。其重要模块Matlab Interface可建立与Matlab的连接。本文以此模块为基础,针对传统的STK场景建模的缺点,利用Matlab软件实现STK可视化场景的自动生成,对机动目标的侦察情况进行仿真,通过Matlab读取STK仿真数据实现对机动目标的覆盖分析,生成分析结果报告,取得了良好的效果。

Satellite Tool Kit is an effective tool to support the whole process simulation of aerospace missions,which can accurately calculate the spatial relationship between specific targets and other related objects,accurately display and analyze the targets of the land and sea in the simulation time or real time. Space and sky targets can also achieve satellite and other load coverage analysis. Its important module Matlab Interface can establish the connection between Matlab and STK. In this paper,aiming at the shortcomings of traditional STK scene modeling,this paper uses Matlab software to realize the automatic generation of STK visual scene,and simulates the reconnaissance of maneuvering target.Analysis of coverage of maneuvering Target by reading STK Simulation data by Matlab,the analysis result report is obtained by Access,which achieves good results.
