中文摘要：
该文提出一种低信杂噪比下弱小舰船目标的检测方法。该方法对回波的慢时间瞬时自相关函数进行锥形尺度变换（Taper Scale Transform,TST）,解除时延和慢时间的耦合。然后将TST后的信号相干积累,达到很好的检测效果。另外,该文分析了交叉项对检测的影响以及尺度因子的选择标准。实测数据的处理结果验证了该方法的有效性。
英文摘要：
In this paper,a new approach based on Taper Scale Transform（TST） is presented for weak ship target detection in the circumstance of strong clutter and noise.By scaling the coordinate of signal instantaneous correlation function,the coupling between slow time and lag time is removed,thus fully coherent integration can be achieved for target detection.The determination of scaling factor and the interference of cross terms related to detection are analyzed.Real data result verifies the effectiveness of the proposed method.
