for stepped-frequency synthetic aperture radar is proposed in this article to compensate the …

The stepped-frequency synthetic aperture radar (SFSAR) has been widely used to obtain
high-range-resolution image. Combining the sub-band echoes to form a wideband signal is …

For the drawbacks of the synthetic bandwidth method based on time-domain back
projection, a novel synthetic bandwidth method based on frequency-domain back projection …

Synthetic aperture radar (SAR) sometimes needs to be imaged with small time bandwidth
product (TBP) for fast observation. As a real-time image algorithm, back-projection algorithm …

In order to achieve a high range resolution and low instantaneous bandwidth, stepped
frequency synthetic aperture radar (SAR) is widely used with stepped-frequency chirps and …

An efficient algorithm based on chirp scaling algorithm (CSA) for terahertz (THz) stepped-
frequency (SF) synthetic aperture radar (SAR) imaging is proposed in this letter. We call this …

The past decades have witnessed an increasing attention for detailed observation with
developing of Synthetic Aperture Radar (SAR). The higher the resolutions of SAR images …

For synthetic aperture radar (SAR) imaging, a stepped-frequency chirp signal is widely used
to obtain ultrahigh range resolution. There are mainly two challenges in the stepped …

This paper presents a synthetic aperture radar (SAR) imaging system using a stepped
