Robust minimum variance multiple‐input multiple‐output radar beamformer
IET Signal Processing, 2013 A robust minimum variance (MV) beamforming approach is proposed for improving the robustness of multiple‐input multiple‐output (MIMO) radar against the mismatches of the steering vector and the finite sample effects. In contrast to existing robust MV beamformers (RMVBs), the proposed RMVB utilises a specific structured model of virtual steering vector (

Phase compensation and processing in multiple-input–multiple-output radars
IET Radar, Sonar & Navigation, 2012 In this study, the issue of phase discontinuity in multiple-input-multiple-output (MIMO) radar systems is analysed and described in detail, together with an efficient way for processing MIMO radar data by means of discrete-time Fourier transform (DFT) fast Fourier transform (FFT). In particular, here it is shown that the phase history of a point target

Bayesian Joint Localization and Tracking Algorithm Using Multiple-Input Multiple-Output Radar
2023 IEEE 9th International Workshop on Computational Advances in Multi-Sensor Adaptive Processing (CAMSAP), 2023 We present a novel joint localization and tracking algorithm for multiple-input multiple-output active radars. The proposed algorithm, which we dub Bayesian localization and tracking (BLaT), relies on approximate Bayesian inference using the mean field approach and processes all available received data to jointly estimate the target’s track and ...

Robust adaptive beamforming for multiple-input multiple-output radar with spatial filtering techniques [PDF]
Signal Processing, 2018 Abstract In this paper, we consider robust adaptive beamformer design for multiple-input multiple-output (MIMO) radar systems. The desired transmit-receive steering vector is estimated through maximizing the output power subject to constraints upon correlation coefficient and steering vector norm. The original nonconvex problem is reformulated as two
