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 inputgray-scale multitarget scenes are given.福建省自然科学基
