An Imaging Method of Moving Target for Sparse Spatial SIMO Radar with Small-squint Angle
摘要
Abstract
The number of antenna elements of single-input multiple-output (SIMO) radar is too many when imaging for moving target with single snapshot. To solve the problem, a new imaging method of moving target for sparse spatial SIMO radar with small-squint angle is proposed by this paper. Firstly, the single snapshot imaging method for SIMO radar with small-squint angle is analyzed in detail. Then, the imaging method based on Compressive Sensing (CS) for sparse spatial SIMO radar with small-squint angle is put forward. Single snapshot imaging for moving target is implemented by this method, which not only can avoid the difficulty of motion compensation aroused by strong accelerated motion or large turn angle motion, but also can reduce the number of antenna, it is the advantage to engineering practice. Finally, the effectiveness and feasibility of this algorithm is validated by the simulative results.关键词
