动态红外景像投影中的辐射度与噪声分析

Radiometric and Noise Analysis in Dynamic IR Scene Projection

针对半实物仿真中(HWIL)动态红外景像投影仪的设计,详细介绍了红外景像投影仪设计中辐射度与噪声方面的一些问题,具体关注了有效黑体温度的计算和影响有效黑体温度的因素,分析了投影仪阵列中处于关闭状态的像元的辐射度,描述了设计过程中不同种类投影仪可能出现的时间与空间噪声。

In view of the design of the infrared scene projector in hardware-in-the-loop （HWIL） simulation, the radiometric and noise problems in the design of the infrared scene projector are presented in detail. The calculation of the effective blackbody temperature and the factors which can affect the effective blackbody temperature in practice are discussed particularly. The radiance from the off-state pixels of the projector array is analysed. The spacial and temporal noise problems which may occur in the design procedure of various infrared scene projectors are described.
