空间目标的红外辐射特性分析一直是比较难的课题,文中提出采用Sinda/G软件和Matlab编程相结合的方法来研究空间目标红外辐射特性。介绍了Sinda/G软件的基本原理,阐述了基于Sinda/G和Matlab实现空间目标红外辐射特性分析的具体流程。以空间球面壳体目标为例,利用该方法得到了目标的红外辐射强度以及跟踪探测器在不同时刻、不同观测方向接收到的红外辐射强度。此方法在研究空间目标红外辐射特性,实现空间目标探测和跟踪方面具有十分重要的意义。
Analysis of the infrared radiation characteristics of the space target has always been a difficult topic. In this paper, the combination of Sinda / G software and Matlab programming is proposed to study the infrared radiation characteristics of the space target. The basic principle of Sinda / G software is introduced, and the specific flow of analyzing infrared radiation characteristics of space target based on Sinda / G and Matlab is expounded. Taking the target of the spherically spherical shell as an example, the infrared radiation intensity of the target and the intensity of the infrared radiation received by the detector at different times and in different observation directions are obtained. This method is of great significance in studying the infrared radiation characteristics of space targets and achieving the detection and tracking of space targets.
