Investigation on techniques of middle-field ISAR imaging based on rotator mode;

基于转台的中场ISAR成像技术研究

The middle-field ISAR imaging by mending curved phase front is as same as the far-field imaging,but can reduce the requirement of measurement distance greatly,with great engineering meanings.

在中场区通过对相位弯曲补偿进行微波成像与远场成像效果相当,且能大大降低对测试距离的要求,所以具有很强的工程应用价值。
