摘要: 介绍了正交子空间投影方法，这种方法可将背景信号从接收到的混合光谱中消除，在此基础上运用匹配跟踪算法自动地进行优化波段的选择，达到选择最佳波段进行目标探测的目的。将其运用到大气外目标探测的问题，得到了较好的探测波段的结果，说明此方法选择优化波段进行目标探测是有效的。Abstract: An orthogonal subspace projection approach is introduced. Using the method, the background radiance can be eliminated from the received mixture signal. Using the matching pursuit algorithm, optimum wavelength bands can be picked out. The aim to detect target can be achieved by choosing the bands. Applying this method to target detection out of the atmosphere, the result has been obtained. It can be approved the method is effective to choose optimum wavelength bands for target detection.
