中文摘要：
ISAR成像是现阶段一种被广泛研究的重要技术。首先阐述了利用距离-多普勒算法对线性调频体制ISAR的成像原理。在此基础上,针对慢速运动目标的特点,提出了基于相位补偿的子孔径拼接处理方法。该方法可以明显改善成像效果。利用滑翔机模型进行仿真验证。其仿真结果证明了其可行性和有效性。
英文摘要：
ISAR imaging is an important technology,which is studied widely.In the paper,first of all,the principle of ISAR imaging with range-Doppler method using chirp signal is revealed.On the basis of that,a new method of connecting different sub-apertures based on characters of low-velocity targets is proposed,which can improve imaging quality obviously.In the method,the phase compensation is effectively employed.Finally,the computer simulations with glider model are carried out.The feasibility and validity of the method can be proved by simulation results.
