分析了半实物仿真试验在红外捕获跟踪设备性能评估中的优势。红外捕获跟踪设备半实物仿真的核心是数字图像的仿真生成工作,针对捕获跟踪设备半实物仿真提出了两种图像生成方法:预先生成的图像生成方法和要素素材预先生成+实时合成的图像生成方法,第一种方法适用于开环仿真试验,第二种方法适用于闭环仿真试验。两种图像生成方法中的要素素材生成、传感器效应仿真均采用基于实测数据的方法,其能够保证运动特性、辐射特性、传感器效应仿真精度,第二种方法会对闭环仿真试验的实时性提供支持。分别针对图像生成的三大过程(要素素材的生成、图像合成、传感器效应仿真)阐述了仿真思路。生成的图像可以充分的考核捕获跟踪设备的性能。
分析瞭半實物倣真試驗在紅外捕穫跟蹤設備性能評估中的優勢。紅外捕穫跟蹤設備半實物倣真的覈心是數字圖像的倣真生成工作,針對捕穫跟蹤設備半實物倣真提齣瞭兩種圖像生成方法:預先生成的圖像生成方法和要素素材預先生成+實時閤成的圖像生成方法,第一種方法適用于開環倣真試驗,第二種方法適用于閉環倣真試驗。兩種圖像生成方法中的要素素材生成、傳感器效應倣真均採用基于實測數據的方法,其能夠保證運動特性、輻射特性、傳感器效應倣真精度,第二種方法會對閉環倣真試驗的實時性提供支持。分彆針對圖像生成的三大過程(要素素材的生成、圖像閤成、傳感器效應倣真)闡述瞭倣真思路。生成的圖像可以充分的攷覈捕穫跟蹤設備的性能。

The advantage of hardware- in- loop simulation for evaluating IR capturing and tracking equipment was analyzed. The most important work of simulation was image generation, two image generation methods for hardware- in- loop simulation of IR capturing and tracking equipment were proposed: image beforehand generation method and element beforehand generation + image synthesis method. The first method was used for loop- open simulation, the second method was used for loop-locked simulation. The elements generation and sensor simulation was based upon test data in both method. The precision of movement characteristic、radiation characteristic and sensor affecting could be ensured by these methods, and by second method, help for the reality of the loop- locked simulation could be supplied. The three processes (elements beforehand generation、image synthesis and sensor simulation) were expounded. The generated image could be used for evaluating capability of IR capturing and tracking equipment.
