海面运动舰船目标的定位检测是军事图像处理领域的一个重要方向，同时海面对光线的折射放射对检测的准确性造成了干扰。本文重点对目标检测法进行研究，分析了算法利弊。为解决目标检测算法对于目标背景的敏感度问题，以及提高算法的实时性，把小波变换运用到目标运动检测中，通过小波变换更新图像背景框图，使实时图像在可变模板背景进行运动物的提取。最后，设计基于DSP的仿真系统，通过实验证明新的方法能较好解决因背景更新以及目标物变形造成的检测误差，提高检测精度。

The detection and localization of moving ship targets on the sea is a very important direction of military image processing. The algorithm accuracy and efficiency are two key performance indicators. The paper research the popular algorithms and analysis the advantages and disadvantages of it. The detail theory and algorithm of a new detection method, which is based on the lifting scheme of wavelet are described. At last, design image processing system based on DSP, the results seem to suggest that the new method be with efficiency and accuracy advantages.
