地面目标光学特征近/远距映射研究

Research on near/far distance mapping of ground target optical features

针对复杂背景环境下的地面特种车辆目标在不同高度距离下的光学目标特征推演变换及探测性能评价问题,基于大气传输理论,应用像元分辨率变换方法和像元幅值变换方法,构建了近/远距离目标特征映射模型;模拟仿真获得了空基和天基不同距离下的地面目标可见光探测图像,提出了基于探测概率的光学隐身性能估算方法.这为实战条件下的地面目标可见光隐身性能分析评估提供了一种技术途径.

Aiming at the optical target feature deduction transformation and detection performance evaluation of ground special vehicle targets in different altitude and distance under complex background environment,this paper is based on the atmospheric transmission theory,and uses the pixel resolution transformation method and the pixel amplitude transformation method to construct the feature mapping model of near/far distance targets.And then,the visible light detection images of ground targets at different air-based and space-based distance are obtained by simulation.Finally,the optical stealth performance estimation method based on detection probability is presented.This provides a technical way for analyzing and evaluating the visible light stealth performance of ground targets under actual combat conditions.
