摘要
Abstract
Frequency-modulated continuous-wave （FMCW） synthetic aperture radar （SAR） is a new imaging radar system,with the advantages such as small size,light weight,high resolution,low power,low probability of intercept, etc. In this paper, the de-chirped FMCW SAR signal model in different imaging conditions is introduced in detail. Then the Range-Doppler （RD） imaging algorithm is presented based on the model, and the azimuth match filter for precise imaging is analyzed. Finally, the correctness and the feasibility of the imaging algorithm are proved by simulation.关键词
