High-resolution and wide-swath synthetic aperture radar (SAR) images can be obtained by
multichannel sampling. However, a nonoptimum pulse-repetition frequency is associated …

Nonuniform sample of SAR signal will bring the noise into the signals, and thus mix the
spectrum of the echo signals with that of the noises, increase ambiguity of the signals, and …

The traditional filter bank algorithm (FBA) for a multichannel synthetic aperture radar (SAR)
system can provide an unambiguous recovery. However, the FBA may result in a seriously …

The technique of multiple apertures in azimuth enables a wide swath synthetic aperture
radar (SAR) with a high azimuth resolution. In a traditional multi-channel SAR system, if the …

Azimuth multi-channel synthetic aperture radar has been widely studied to realize high
resolution wide swath imaging. Spectrum reconstruction algorithm deals with the main-lobe …

The technique of multiple apertures in azimuth enables a wide swath synthetic aperture
radar (SAR) with high azimuth resolution. In a traditional multi-channel SAR system, a …

Azimuth ambiguity occurs in synthetic aperture radar (SAR) systems due to the well-known
constraint of minimum antenna area, particularly at high resolutions and wide swaths. A …

Multichannel synthetic aperture radar (SAR) signal reconstruction methods can effectively
suppress azimuth ambiguities and achieve high-resolution wide-swath imaging. However …

The traditional spectrum reconstruction algorithm for nonuniform sampling of a displaced
phase center antenna (DPCA) synthetic aperture radar (SAR) system can provide an …

For the azimuth multichannel synthetic aperture radar (SAR), nonuniform sampling is
common since the pulse-repetition frequency cannot be selected arbitrarily, which leads to …
