提出一种新的采用高通滤波的二元联合变换相关器。这种相关器与一般的二元联合变换相关器的差别在于联合功率谱作二元处理之前先进行高通滤波。使用这种技术，可以产生比二元联合变换相关器更好的相关输出性能。给出对含有灰度级物体的输入景物的计算机模拟结果。 A new binary joint transform correlator using high-pass filter is proposed. The difference between this kind of correlator and the general binary joint transform correlator is that the joint power spectrum is subjected to high-pass filtering before binary processing. Using this technique, it is possible to produce better correlation output performance than the binary joint transform correlator. The computer simulation results of input scenes containing objects with gray level are given.
