提出了一种递增结构能量参数的Markov随机场模型的合成孔径雷达图像目标检测算法,利用模拟退火优化方法,获得最大后验概率准则下的目标检测结果。实验结果表明,该算法不仅能有效减少斑点噪声及背景杂波的影响,而且还可以排除具有较强回波的角反射器的干扰。

Based on MRF in which increasing structure energy parameter is adopted,an algorithm of target recognition for SAR images was proposed in this paper.Using MAP(Maximum a Posterior) criterion,the target recognition result is obtained by applying SA(Simulated Annealing) algorithm to maximize the posterior distribution.The test results show this algorithm not only reduces the influence of speckle noise and background clutter effectively but also removes disturbance of angle reflectors with strong echo.
