摘　　要：为了更好地应对高光谱成像技术对伪装的威胁,本文从目标探测角度出发,以约束能量最小化(CEM)算法探测,自适应余弦一致性评估(ACE)算法探测和异常探测(RXD)算法探测分别研究了先验光谱信息有无和先验光谱有误情况下对军事小目标探测的影响。通过经探测结果对比分析,可以得出先验光谱信息的有无将会直接影响到军事目标探测的效率,而先验信息的有误将会影响到军事目标的精确度。其相关结论也为伪装应对高光谱成像技术提供了可借鉴的意义。In order to deal with the threat of hyperspectral imaging technique on camouflage,the impact of priori information of target spectrum on target detection was investigated.Different detection methods,including constrained energy minimization(CEM)algorithm,adaptive Cosine conformity assessment(ACE)algorithm and anomaly detection(RXD)algorithm,were used to detect targets in a hyperspectral image with or without priori information.Through comparative analysis,the results indicated that target detection efficiency was seriously affected by the priori information,and any mistake of the priori could greatly reduce the detection rate.This conclusion can be helpful for the technology of camouflage and stealth.
