Imaging method for FMCW SAR with diving acceleration based on ENCS algorithm

Abstract

The frequency modulated continuous wave (FMCW) synthetic aperture radar (SAR) has the properties of compact size, lightweight, low cost and low power dissipation, which provides great potential in the application of precision guidance. This paper presents an imaging method of FMCW SAR with diving acceleration. The series reversion algorithm is used to evaluate the accurate expression of the received signal in Doppler frequency domain, and an extended nonlinear chirp scaling (ENCS) algorithm is proposed for compensating the azimuth variance phase error. The simulation is presented to show the effectiveness of the proposed method.
