Robust approaches to remote calibration of a transmitting array [PDF]

, 2010
We consider the problem of estimating the gains and phases of the RF channels of a M-element transmitting array, based on a calibration procedure where M orthogonal signals are sent through M orthogonal beams and received on a single antenna.

A Grid-Less Total Variation Minimization-Based Space-Time Adaptive Processing for Airborne Radar

IEEE Access, 2020
Sparse recovery (SR) based space-time adaptive processing (STAP) has attracted much attention due to its small requirement of snapshots in the estimation of the clutter plus noise covariance matrix (CNCM).

Distributed MVDR Beamformer Based on Distributed Steering Vector Estimation in Acoustic Sensor Network

Electronics Letters
Distributed beamformers have shown great potential for speech enhancement in acoustic sensor network. In this paper, we propose a novel distributed minimum variance distortionless response (MVDR) beamformer, where the network‐wide steering vector used ...

Transmit Beamspace Design for Bistatic MIMO Radar With Improved Angle Estimation

IEEE Access, 2019
The energy dispersion of traditional bistatic multiple-input multiple-output (MIMO) radar severely degrades the angle estimation performance. To overcome this limitation, we propose to design the transmit beamspace matrix and apply the design result to ...

Tensor-Based Reduced-Dimension MUSIC Method for Parameter Estimation in Monostatic FDA-MIMO Radar

Remote Sensing, 2021
Frequency diverse array (FDA) radar has attracted much attention due to the angle and range dependence of the beam pattern. Multiple-input-multiple-output (MIMO) radar has high degrees of freedom (DOF) and spatial resolution. The FDA-MIMO radar, a hybrid
