As current airborne SAR systems aiming to produce SAR imagery at resolution less than 0.1
m, attaining ultrawideband signal become a difficult problem. Synthetic bandwidth based on …

The stepped-frequency waveform is used to obtain large effective bandwidth for high range
resolution by transmitting the pulses with sequentially changing carrier frequency, so that is …

To achieve high range resolution using the stepped frequency chirp signal, two or more
chirp waveforms are sequentially transmitted and received at stepped carrier frequencies in …

摘要 This work addresses the study of bandwidth management and image formation for
airborne SAR imaging with 0.1 m resolution. The frequency domain synthetic bandwidth …

A highly squint stepped frequency SAR imaging algorithm is introduced in this paper. The
first step of this algorithm is sub-band 2-D imaging, and then range broadband is …
