【摘要】:針對當前紅外探測系統(tǒng)作用距離模型中出現(xiàn)的精度及適用性問題,引入切合實際的波段探測方法,從目標紅外輻射、大氣衰減及探測系統(tǒng)性能三方面進行建模,并通過迭代算法進行仿真,得到目標輻射強度及探測距離特性曲線。仿真結果顯示,目標最大輻射強度及最遠距離觀察角度均出現(xiàn)在尾后偏離中心處。在對目標全向輻射及探測距離的仿真計算中,得到相似的結論。在與同類文獻提供的可靠數(shù)據(jù)進行比較后,發(fā)現(xiàn)該優(yōu)化模型接近實際情況,可以應用于實際工程。
[Abstract]:Aiming at the problems of accuracy and applicability in the current operating range model of infrared detection system, a practical wave band detection method is introduced to model the target infrared radiation, atmospheric attenuation and the performance of the detection system. The characteristic curves of target radiation intensity and detection range are obtained by iterative algorithm. The simulation results show that the maximum radiation intensity and the most remote observation angle appear behind the tail and away from the center. A similar conclusion is obtained in the simulation calculation of the omnidirectional radiation and detection distance of the target. After comparing with the reliable data provided by the same literature, it is found that the optimization model is close to the actual situation and can be applied to practical engineering.
