摘　　要：光电联合变换相关器具有实时处理光学图像能力,因此可用于景像匹配系统。提出了一种适合于光电联合变换相关器的相关算法,该算法利用实数傅里叶矩阵的对称性,减少了运算中的存储和计算量,通过改进频谱的滤波算法,提高了相关结果的输出信噪比,从而提高了匹配精度。Opto-electronic joint transform correlator has real-time ability for processing optical images, so it can be used in scene matching system. A correlation algorithm fitted for optical electronic joint transform correlator is proposed. This algorithm can work with less memory and less calculation, and adopt real number symmetry of Fourier matrix to increase the signal to noise ratio （SNR） of correlation results and improve the matching precision.
