摘要
对于海面目标的检测,由于雷达波束擦地角低,海杂波很强,且由于雷达目标等效截面积小,信噪比低,常规的门限检测方法虚警概率高、检测概率低,有必要探讨新的检测方法。采用Hough变换将同一目标航迹上的回波能量进行累积的方法,对模拟的(分别利用K分布、对数正态分布、高斯分布和韦伯分布模拟海杂波,并人工加入单个或多个运动目标信息来合成雷达回波)或真实的雷达回波数据进行处理,并通过Hough反变换求取目标航迹。最后,在该算法的基础上,使用Matlab提供的界面设计工作台,制作出适于人机交互的海面目标检测综合仿真平台。
As the grazing angle of the radar beam and the RCS of sea surface targets are little, and the sea clutter is strong and the SNR is low, the normal target detection method has a high false alarm probability and a low detection probability. Therefore, new methods should be advanced. In this paper, Hough transform was used to accumulate power of radar echo from the same target track, and Hough opp-transform was used to process the simulative （synthesized by single target information or multiple targets informa- tion which is input by hand added to random number with the distribution of K distribution, Log-normal distribution, Gauss distribution, Weibull distribution） or real radar echo to get the target track. Finally, using the methods above, a user interface is made on the Layout Editor of Matlab for the convenience of users.
