A Novel Range-Azimuth Joint Modulation Scheme for Range Ambiguity Suppression

IEEE Transactions on Geoscience and Remote Sensing, 2022
Range ambiguity is a technical challenge for current spaceborne synthetic aperture radar (SAR) systems. To this end, a novel range-azimuth joint modulation transmission scheme is proposed, and the corresponding imaging processing and performance analysis are detailed.

Range-ambiguity artifact in abdominal ultrasound

Journal of Medical Ultrasonics, 2019
Range-ambiguity artifacts (RAAs) are an erroneous mapping of returning echoes into a composite picture. The purpose of this review was to illustrate the mechanism of RAAs and to present the diagnostic problems caused by RAAs. RAA features differ slightly from organ to organ.

Ultra-rapid dual-comb ranging with an extended non-ambiguity range

Optics Letters, 2022
In this Letter, we report a scheme that combines time-of-flight (ToF) ranging detection of multi-repetition-rate pulses with asymmetric dual-comb ranging (DCR) measurement. Notably, this combination extends the non-ambiguity range (NAR) of the DCR method without sacrificing its refresh rate and distance precision.

Long-range photon-efficient 3D imaging without range ambiguity

Optics Letters, 2023
Single-photon light detection and ranging (LiDAR) has broad applications ranging from remote sensing to target recognition. In most cases, however, the repetition period of the pulsed laser limits the maximum distance that can be unambiguously determined. The relative distances are normally obtained using a depth map.

Range ambiguity in pulsed doppler ultrasound: The ambiguity clarified?

Journal of Clinical Ultrasound, 1985
AbstractPulsed Doppler ultrasound (PW) can be used to determine the location of frequency shifts within the cardiac chambers or great vessels. However, it is possible to record similar frequency shifts at sample volume locations distal to their original site; this is referred to as range ambiguity (RA).
