Multibeam single frequency synthetic aperture radar processor for imaging separate range swaths [PDF]

open access: yes, 1982
A single-frequency multibeam synthetic aperture radar for large swath imaging is disclosed. Each beam illuminates a separate ""footprint'' (i.e., range and azimuth interval).

Remote temperature profiling in the troposphere and stratosphere by the radio-acoustic sounding technique [PDF]

open access: yes, 1986
Radar application of the radio-acoustic sounding technique uses the Doppler frequency shift of radar echoes returning from the atmospheric wave structure, in association with a traveling acoustic pulse transmitted from the ground, to determine the speed ...

Machine Learning Doppler‐Tolerant One‐Bit Radar Detectors

open access: yesIET Radar, Sonar & Navigation
Doppler‐tolerant waveforms are some of the most common radar waveforms used in practice. However, their deterministic and repetitive nature impedes control of mutual interference when multiple radars operate in close proximity. Noise radar technology may
