Beamforming issues in modern MIMO Radars with Doppler [PDF]

open access: yes, 2006
In traditional beamforming radar systems, the transmitting antennas send coherent waveforms which form a highly focused beam. In the MIMO radar system, the transmitter sends noncoherent (possibly orthogonal) broad (possibly omni-directional) waveforms ...

Non‐stationary clutter suppression method for bistatic airborne radar based on adaptive segmentation and space–time compensation

open access: yesIET Radar, Sonar & Navigation, 2021
Bistatic airborne radar has excellent performance due to the separate transmitter and receiver, but its clutter distribution is usually non‐stationary, which causes the performance of the traditional Space time adaptive processing (STAP) method to fail ...

Dimensionality reduction bistatic radar clutter suppression technique based on three-dimensional cross-beam

open access: yesXibei Gongye Daxue Xuebao, 2023
Aiming at the problem that the non-stationary of airborne bistatic radar clutter reduces the performance of traditional clutter suppression algorithm, this paper first formulates airborne bistatic radar clutter model, and then analyzes the bistatic radar

Terahertz High-resolution Radar Clutter Measurement and Analysis

open access: yesLeida xuebao, 2015
The clutter characteristics of terahertz high-resolution radar are essential for terahertz radar detection. This study analyzes the traditional clutter probabilistic model and the corresponding parametric estimation methods.

Radar small/mini target detection technology in strong clutter environment

open access: yesThe Journal of Engineering, 2019
A method of radar small/mini target wavelet transform and principal component analysis in strong clutter environment is suggested. Focusing on the situation that the small/mini target in the strong clutter environment is swamped by clutter, traditional ...

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.
