Three-dimensional Multiple-Input Multiple-Output Radar Imaging Method Based on Integration of Multi-snapshot Images

open access: yesLeida xuebao, 2020
To improve the cross-range resolution of three-dimensional (3-D) images obtained along the direction of movement by Multiple-Input Mmultiple-Output (MIMO) radar, a novel MIMO-ISAR 3-D imaging method that combines multi-snapshot images is proposed.

A dilating and embedding scheme for constructing sparse MIMO radar array

open access: yesElectronics Letters, 2023
In this letter, a dilating and embedding scheme for constructing sparse multiple‐input and multiple‐output radar arrays is addressed, which seeks to increase the uniform degrees of freedom (uDOFs) and reduce the mutual coupling effects for a given number

Robust adaptive beamforming for multiple-input multiple-output radar with spatial filtering techniques [PDF]

open access: yesSignal 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

Echo correlation analysis in diversity multiple‐input multiple‐output radars

open access: yesIET Radar, Sonar & Navigation, 2016
The existing circular target model has a huge limitation which just represents the target angle or frequency interval with respect to the station, but ignores the influence of observed direction. To solve this problem, in this study the correlation coefficient for rectangular scattering model which has two parameters of width and length in spatial and ...

Generation of Uncorrelated Multichannel Chaos by Electrical Heterodyning for Multiple-Input–Multiple-Output Chaos Radar Application

open access: yesIEEE Photonics Journal, 2016
Multiple-input–multiple-output (MIMO) radar has received much attention in recent years for its great ability in imaging. However, the essence of MIMO radar has not been fully implemented due to the lack of proper transmission waveforms.
