Subsurface CW interference radar

open access: yesElectronics Letters, 1995
A new subsurface CW (continuous wave) interference radar having the great advantage of detecting a fine shallow target is presented. The horizontal location of the target submerged in a dissipative half-space may be detected easily by using the symmetry of the measured electric field pattern.

Velocity Dealiased Spectral Estimators of Range Migrating Targets using a Single Low-PRF Wideband Waveform [PDF]

open access: yes, 2013
Wideband radars are promising systems that may provide numerous advantages, like simultaneous detection of slow and fast moving targets, high range-velocity resolution classification, and electronic countermeasures.

FM-CW Snow RADAR

open access: yesIJIREEICE, 2015
Global warming is one of the most important issues facing humanity. The depth and extent of sea-ice are clear indicators of global warming. Snow cover on sea-ice is an important variable that affects the volume of sea-ice and indirectly global warming as a whole. This paper discusses the design of snow radar.

Classification of Interference Signal for Automotive Radar Systems With Convolutional Neural Network

open access: yesIEEE Access, 2020
When a radar signal generated by another vehicle arrives at an ego-vehicle, mutual interference occurs, which can seriously degrade the detection performance of the radar.

Design and Applications of Multi-Frequency Holographic Subsurface Radar: Review and Case Histories

open access: yesRemote Sensing, 2021
Holographic subsurface radar (HSR) is not currently in widespread usage. This is due to a historical perspective in the ground-penetrating radar (GPR) community that the high attenuation of electromagnetic waves in most media of interest and the ...

Air-borne linear frequency modulation range interrupted continuous-wave SAR for high-resolution imaging

open access: yesThe Journal of Engineering, 2019
To avoid two apertures adopted in air-borne continuous-wave (CW) synthetic aperture radar (SAR) systems, the novel air-borne linear frequency modulation range interrupted continuous wave (LFMRICW) SAR imaging mode is presented here.
