A Novel Multi-Beam SAR Two-Dimensional Ambiguity Suppression Method Based on Azimuth Phase Coding
Remote SensingIn order to address the problems of range ambiguity and azimuth ambiguity in the wide-swath imaging of synthetic aperture radar (SAR), this paper proposes a multi-beam SAR two-dimensional ambiguity suppression method based on azimuth phase coding (APC ...

Mixing Matrix Calibration for BSS Range Ambiguity Suppression in Multichannel SAR Systems [PDF]
IEEE Geoscience and Remote Sensing LettersA significant level of range ambiguity disturbance may affect high-resolution wide-swath spaceborne synthetic aperture radar (SAR) systems with multiple elevation receive beams. To overcome this limitation, a promising approach, based on the higher order blind source separation (BSS), was recently proposed.

Remote SensingThe non-stationary clutter of space-based early warning radar (SBEWR) is more serious than that of airborne early warning radar. This phenomenon is primarily attributed to the Earth’s rotation and range ambiguity.

A Proposed Algorithm for Range Ambiguities Suppression in Multi-Static Sar [PDF]
IGARSS 2022 - 2022 IEEE International Geoscience and Remote Sensing Symposium, 2022 In a conventional synthetic aperture radar (SAR), good azimuth resolution and wide coverage pose contradicting requirements for the pulse repetition frequency (PRF). With a PRF tailored to a desired resolution, range ambiguities is then the main obstacle to a wide swath imaging.

Range‐ambiguity suppression for noise radar in cluttered environment via sparse recovery
Electronics Letters, 2021 Range ambiguity suppression is a significant problem in traditional pulse‐Doppler radar systems, especially when the pulse repetition frequency is set high to avoid Doppler ambiguity. One possible way to deal with such problem is to apply the noise radar

Range ambiguity clutter suppression for bistatic STAP radar [PDF]
EURASIP Journal on Advances in Signal Processing, 2013 Bistatic pulse-Doppler airborne radar has desirable properties such as the low probability of detection by other radars relative to its monostatic counterpart. However, the clutter characteristics of bistatic airborne radar are more complex than those of monostatic airborne radar.

Precise Ambiguity Performance Evaluation for Spaceborne SAR with Diverse Waveforms
Remote Sensing, 2023 The ambiguity suppression is a technical challenge for the present generation of spaceborne synthetic aperture radar (SAR) systems since this kind of suppression does not take the high spatial resolution and wide coverage into account simultaneously. The
