Main work focused on the motion compensation method in view of FJB used for ISAR imaging .
另外还研究了调频步进信号的ISAR运动补偿方法，通过对模拟目标的成像说明这种方法的实用性。

NAG model and FJB damage degree function model based on statistical micro-damage mechanics have a good ability of description of the process of damage evolution , and the computed free-surface velocity profiles consist with the experimental measurements very well .
从材料损伤断裂物理本质出发，采用微损伤统计方法得到的NAG模型和封加波损伤度函数模型，能很好地再现实测的自由面速度剖面，数值计算结果与实验吻合很好。
