本文首先研究了ISAR成像的基本原理，在理想转台模型的基础上对距离-多普勒(R-D)成像算法做了分析，对目前常用的运动补偿技术进行了对比和研究，并将这些技术用于雅克-42飞机的实测数据中。然后，论文系统地论述了压缩感知主体理论，重点对信号重构中的基追踪(BP)算法和正交匹配追踪(OMP)算法进行了深入的研究和讨论，并通过正弦信号的仿真结果验证了两种方法的有效性。(Firstly, the basic principle of ISAR imaging study, based on an ideal model for distance turntable- Doppler (RD) imaging algorithm to do the analysis of the motion compensation techniques currently used are compared and studied, and the use of these technologies in the measured data in the Yak-42 aircraft. Then, the paper systematically discusses the theory of compressed sensing body, focusing on the signal reconstruction of the base track (BP) algorithm and orthogonal matching pursuit (OMP) algorithm is conducted in-depth studies and discussions, and the simulation results verify the sinusoidal signal the effectiveness of the two methods.)
