摘要
提出一种空间性能指标和辐射性能指标相结合的基于点目标的雷达强度影像质量评价方法。利用空间分辨率、峰值旁瓣比和积分旁瓣比指标对雷达影像质量进行定性评价,并利用仿真和实测数据进行实验分析,结果表明,该方法具有较好的有效性和可操作性。
Based on pinpoint target,the spatial and radial character was used for SAR image quality evaluation.With space resolution,ratio of peak value side lobe and ratio of integral side lobe,quanlitative analysis for SAR image was achieved though simulation and experiment.The results indicated that the evaluation was effective and exercisable.
