基于有序数据可变索引的舰船目标检测方法研究

Research on ship target detection method based on ordered data variable index

舰船目标的检测与识别技术有重要作用,一方面,在海上交通管理和航线疏导上,舰船目标检测技术可以提供舰船准确的航行速度等信息,另一方面,海上舰船检测广泛应用于军事领域的敌方舰船侦察、锁定等,对保护海上领土有重要意义。本文主要研究了合成孔径雷达(SAR)技术,针对SAR技术舰船目标图像特征提取、噪声过滤等问题,采用一种有序数据可变索引技术,提高了舰船合成孔径雷达SAR图像处理的精度,并进行了海上舰船目标的仿真试验。

The detection and recognition technology of ship target plays an important role.On the one hand,in maritime traffic management and route guidance,ship target detection technology can provide accurate navigation speed and other information.On the other hand,the detection technology of ship on the sea is widely used in military field,such as enemy ship reconnaissance and lock-in,which is of great significance for the protection of maritime territory.In this paper,synthetic aperture radar(SAR)technology is mainly studied.Aiming at the problems of feature extraction and noise filtering of ship target image in SAR technology,an ordered data variable index technology is adopted to improve the accuracy of SAR image processing of ship synthetic aperture radar,and the simulation test of ship target at sea is carried out.
