ISAR
:近距离目标超高分辨率微波成像技术在安全检测、非破坏性控制、生物医学等领域中有着非常重要的应用
价值和广阔的应用前景。该文利用基于窄脉冲形式的超宽带时域雷达系统研究近距离目标的高分辨率ISAR成像,
给出了仿真和实测结果。利用转台旋转目标,基于超宽带脉冲源和超宽带收发天线以及高性能取样示波器,配以同
步触发脉冲和自行研发的数据采集软件,搭建了该时域雷达实验系统,提出了准确获取目标回波信息的实验条件,
和实现回波延时精确校正的误差补偿方法。并针对采样时间窗内的杂波干扰,讨论了时域后向投影算法(Back
Projection,BP)与背景对消技术相结合的成像算法,实现了分辨率为 8 mm 的近距离目标的成像,准确地反映了
目标的位置、形状和大小等信息。( The high resolution imaging of near field targets are interesting for security, non-destructive control and
biomedical application. In this paper, high resolution near field ISAR imaging is implemented using Ultra Wide
Band (UWB) time domain radar system. Simulation and experiment are both conducted. The target is rotated by
turntable. The system is built based on the UWB pulse source, UWB antennas, high performance sampling
oscillograph, synchronous trigger pulse and proper motion study data acquisition software. Experiment condition
and delay errors compensation method are presented to obtain accurate echo information of the target. And Back
Projection (BP) combined with background cancel algorithm is discussed considering the clutter interference in
time window. )
