摘要
近年来,利用SAR图像进行舰船目标检测是实现海洋监视、渔业管控的重要手段。我国领海广阔,海洋资源丰富,开展SAR图像舰船目标检测研究具有重要意义。从已有的舰船目标检测系统和检测算法可知,如何在保持检测率的条件下尽可能地减少虚警和提高算法效率是开展SAR图像舰船目标检测研究的重要指标。当前最常用的一类SAR图像舰船目标检测算法是基于统计模型的CFAR方法,本文即围绕此类方法开展研究。
     分析海洋杂波的统计特性是基于统计模型的CFAR检测方法的基础。本文首先研究了SAR图像海洋杂波的统计特性,给出统计建模的一般步骤和拟合优度评价准则,评估了各种分布模型对遥感卫星一号SAR图像海杂波分布的拟合性能。
     基于统计模型的CFAR是一种能够根据局部杂波统计特性计算检测阈值的自适应检测方法。根据背景杂波的统计特性,其检测性能可以从杂波分布模型和检测器两方面得以改进,本文首先总结了基于各种分布模型和不同检测器的CFAR检测方法,其次对基于K分布的CA-CFAR检测算法作了重点分析,并对比了几种基于统计模型CFAR方法在仿真K分布杂波环境中的理论性能。最后,针对遥感卫星一号海洋图像,将基于K分布的CA-CFAR和基于高斯、韦布尔、对数正态分布的CFAR检测算法作了对比实验。实验结果表明,基于K分布的CA-CFAR方法在保证检测率的同时有效地减少了虚警,检测性能优于其他几种基于统计模型的CFAR方法。
     实际的舰船目标检测系统要求检测算法具有近实时性,本文对提高检测算法的效率也进行了研究。在分析已有快速检测算法的处理思路基础上,结合前文的工作,本文提出了一种基于两级CFAR级联的舰船目标快速检测算法,分析了第一级CFAR中分别采用高斯、韦布尔、对数正态分布时快速算法的检测性能和算法效率,并由对实测图像的实验验证了其检测性能。基于两级CFAR级联的舰船目标快速算法与基于K分布的CA-CFAR方法检测性能相当,但算法效率更能满足检测系统的实时性要求。
Recently, ship detection on Synthetic Aperture Radar (SAR) imagery is an important way of ocean surveillance and fishing monitoring. China has large ocean which is full of resources. It is of grate significance in developing ship detection researchment on SAR imagery. There are two criterions of developing researches of ship detection on SAR imagery: how to reduce the false alarms and raise detection efficiency under a certain detection rate. While the algorithms of Constant False Alarm Rate (CFAR) based on statistical models are widely used in SAR imagery ship detection, this paper mainly studies this kind of methods.
     Statistical characteristic analyze is the basic of CFAR detection algorithms based on statistic models. This paper studies the statistical characteristics of SAR sea clutter, presents the setup of statistical modeling and the criterions of model fit performance, and assesses several models’modeling performances to SAR imagery of Remote Sensing-1.
     The method of CFAR based on statistical model has the ability of automatic calculating detection threshold according to sea clutter’s local statistical characteristics. The detection performance can be improved from both using more accurate sea clutter statistical model and more suited detector. Therefore, the CFAR detection algorithms based on varies statistical models and detectors are summarized. After that, particular analyses are made on the CA-CFAR detection algorithm based on K distribution. Its theritical performance is compared with CFAR methods based on several other statistical models. Finally, the CFAR algorithms based on K, Gauss, Weibull and Log-normal are demonstrated on Remote Sensing-1 SAR imagery. The results review that the CA-CFAR detection algorithm based on K distribution not only guarantees detection rate but also generates fewer false alarms. It performs better than CFAR methods based on other statistical models.
     Detection algorithms employed by practical ship detection systems are always demanded for real-time calculation. Therefore, this paper also investigates on improving detection algorithms’efficiencies. A fast detection algorithm based on two-stage conjuncted CFAR is presented. While gauss, Weibull and Log-normal are used in the first stage CFAR separately, performance of the fast algorithm is explicated. Experiment results on field SAR imagery review that, while it satisfies the real-time demand of practical systems better, the proposed fast algorithm has almost the same detection performance with the CA-CFAR detection algorithm based on K distribution.
