| 摘 要： | 运用傅里叶分析方法，利用水平方向、垂直方向、45°方向和135°方向直线的频域模板对侧扫声纳图像在4个方向上进行投影分解，根据子图像在4个方向上投影的能量和，设定门限判断有无目标，并粗略估计目标的位置。实验结果证明，该方法对于纹理较强的侧扫声纳图像中感兴趣区域(目标)的检测有较好的效果。

| Abstract: | This paper presents a Fourier analysis method for target detection in side-scan image. Using horizon line, vertical line, slope 45° line and slope 135° line spectral mask, the projection of side-scan sonar image in these orientation is obtained. Based on the sum of energy of four orientation projections, a threshold is set to judge target existing, and the position of target is also given. Results show that the method has a perfect performance for regions of interest （target） detection of side-scan sonar image with strong texture. |
