摘　　要：针对空中目标的探测与隐身对抗问题,提出了一种新的基于背景杂波估计的目标探测波段选择方法,基于光线追迹的计算机图形渲染技术,建立地球表面背景-大气-飞机目标耦合辐射模型,采用POE杂波尺度,基于信杂比(SCR)模型确定探测波段的选择宽度。将所选择的探测波段应用于飞机顶视探测,仿真结果显示基于背景杂波估计的目标探测波段选择方法能有效增加探测波段宽度,从而提高探测性能。Aiming at the detection and stealth countermeasures of aircraft targets,the paper proposed a new band selection method for target detection based on background clutter estimation.The radiation model which coupled the characteristics of earth surface,atmosphere and aircraft targets is established by using ray tracing(a computer graphics rendering technique).Base on the POE clutter level,a signal to clutter(SCR)model is built to determine the width of selected band.Applied the selected band to the top-view detection of aircraft,the results indicate that our new band selection method can improve the width of the detection band and the system's performance.
