摘要
舰船检测与监视有着广泛的军事和民用意义,而SAR图像是舰船检测的有效手段。针对双参数CFAR算法存在的问题,本文提出了一种基于目标先验知识的二次恒虚警检测(CFAR)算法,能自适应的调整检测窗口的大小,有效提高算法的效率。实验证明,该算法在效率和精度方面都有较大提高。
Ship detection and surveillance are of great significance in military and civilian domain,for which SAR as an efficient method.To overcome the drawbacks of two parameter CFAR algorithm,In this paper,a two-step CFAR algorithm based on target＇s knowledge is proposed.It can adjust the size of the window,and improve the efficiency.A number of experiments demonstrate the efficiency,accuracy of the approach.
