Ground clutter suppression method based on FNN for dual-polarisation weather radar

open access: yesThe Journal of Engineering, 2019
Conventional clutter suppression methods in the field of precipitation detection generally use fixed parameters, resulting in poor clutter suppression in complex weather conditions and regional environments.

Ground clutter simulation for airborne forward-looking multi-channel LFMCW radar

open access: yesThe Journal of Engineering, 2019
Ground clutter is a crucial factor that affects the detection performance of the airborne forward-looking multi-channel linear frequency modulated continuous wave (LFMCW) radar, so the distribution characteristics of studying the ground clutter plays an ...

Modeling of Monopulse Radar Signals Reflected from Ground Clutter in a Time Domain Considering Doppler Effects [PDF]

open access: yesJournal of Electromagnetic Engineering and Science, 2020
To evaluate the performance of a monopulse radar system, it is necessary to accurately model radar return signals from the ground surface in a time domain.

Ground clutter cancellation in incoherent radars: solutions for EISCAT Svalbard radar [PDF]

open access: yesAnnales Geophysicae, 2000
Incoherent scatter radars measure ionosphere parameters using modified Thomson scatter from free electrons in the target (see e.g. Hagfors, 1997). The integrated cross section of the ionospheric scatterers is extremely small and the measurements can ...

General space-time clutter model for multi-channel airborne radar

open access: yesThe Journal of Engineering, 2019
Ground clutter of looking-down airborne radar is spread in Doppler because of the platform motion, and thus the interested moving targets may be masked by the ground clutter.

Forward-Looking Super-Resolution Imaging for Sea-Surface Target with Multi-Prior Bayesian Method

open access: yesRemote Sensing, 2021
Traditional forward-looking super-resolution methods mainly concentrate on enhancing the resolution with ground clutter or no clutter scenes. However, sea clutter exists in the sea-surface target imaging, as well as ground clutter when the imaging scene ...

Ground Clutter Removal in GPR Surveys

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2014
In GPR prospecting, strong reflections due to the background material interface can hinder the detection of localized buried scatterers, especially when the targets are close (in terms of probing wavelength) to the interface. Moreover, signals due to objects located outside the investigated domain and occurring in the observation time window may ...

Research on Strong Clutter Suppression for Gaofen-3 Dual-Channel SAR/GMTI

open access: yesSensors, 2018
In spaceborne synthetic aperture radar (SAR), moving targets are almost buried in ground clutter due to the wide clutter Doppler spectrum and the restricted pulse repetition frequency (PRF), which increases the difficulty of moving target detection ...

Intelligent Suppression Method for Ionospheric Clutter Based on Clustering and Greedy Strategy

open access: yesLeida xuebao, 2020
Clutter is a term used for unwanted echoes in electronic systems, particularly in reference to radars. Such echoes are typically returned from ground, sea, rain, animals/insects, chaff, and atmospheric turbulences, and can cause serious performance ...

Bistatic Forward-Looking SAR Moving Target Detection Method Based on Joint Clutter Cancellation in Echo-Image Domain with Three Receiving Channels

open access: yesSensors, 2018
In bistatic forward-looking synthetic aperture radar (BFSAR) ground moving target detection (GMTD), the suppression of the strong and heterogeneous ground clutter is one of the most crucial and challenging issues. Due to the bistatic forward-looking mode
