基于FMCW的弹载SAR俯冲成像方法研究
Study on the Diving Imaging Method for Missile-Borne SAR Based on FMCW
摘要
Abstract
The frequency modulated continuous wave (FMCW) synthetic aperture radar (SAR) has the properties of compact size, lightweight, low cost and low power dissipation and therefore provides great potential in the application of precision guidance. This paper proposes an imaging method for missile-borne FMCW SAR based on the movement characteristic of the missile-borne FMCW SAR with diving. The range walk is corrected in the time domain. Then the return signal expression in the Doppler frequency domain is deduced via the method of series reversion. Some penalty functions are constructed to obtain the 2-D imaging via analyzing the expression. Finally, the imaging simulations of point target and scene are given for validating the theoretical derivation and the effectiveness of the proposed imaging method.关键词
