摘　　要：提出一种用特征物功率谱取阈值的新型二元联合变换相关器。与传统的联合变换相关器相比较 ,它有高光能效率、高鉴别率和输入空间宽带的优点 ;与现行的二元联合变换相关器相比较 ,它有鉴别率高和不需靶物功率谱测量的特点 。A novel binary joint transform correlator thresholding with reference power spectrum only is proposed. As compared with conventional joint transform correlator, it has the advantages of high light efficiency, excellent discrimination capability and improved input space bandwidth. In a comparison with existing binary joint transform correlator, it possesses higher discrimination capability, and the measurement of the target power spectrum is avoided. Therefore it is a convenient joint transform correlator with high performance merits.
