摘要
An infrared radiation spectral characteristic simulation analysis method for a moving target. The method comprises: firstly, establishing a three-dimensional geometric model for a moving target, and dividing the target according to regions; establishing a temperature distribution model of the target, and calculating temperatures of various points on a surface of the target under different observation angles; then establishing an infrared atmospheric transmission model, and calculating atmospheric transmittance and atmospheric path radiation; setting various parameters of a measurement system and the moving target; calculating radiation energy of an image space of the moving target by using the established target temperature distribution model and infrared radiation transmission model; finally, calculating infrared radiation energy of a point target and a plane target respectively, and drawing a corresponding radiation spectral curve. The infrared radiation spectral characteristic simulation analysis method for a moving target is simple, and considered factors are relatively comprehensive; and data can be provided for subsequent detection, tracking and identification of a target.
