根据啁啾编码的原理和高通滤波的方法.提出使用啁啾编码的高通滤波的联合变换相关器作多目标检测。使用这种方法.可使所想要的参考图像和目标像之间的互相关峰与不想要的直流项、各目标图像之间的互相关峰以及谐波峰输出在不同的平面上,从而提高对多目标检测的准确度,给出对具有灰度级的多目标输入景物的计算机模拟结果。

Based on the chirp-encoding and high Pass filtering, the multitarget detectionusing a chirp-encoded joint transform correlator with high pass filtering is proposed. Thistechnique focuses the desired cross correlation terms between the reference image and thetarget images and the undesired terms, including D. C. term, self- correlation termsbetween the target images and various higher-order correlation terms, onto separated outputplanes. Thus it has higher accuracy of detection. Computer simulation results for the input gray-scale multitarget scenes are given.
