Beamforming in MIMO Radar using Coprime Array

2018 2nd International Conference on Electronics, Materials Engineering & Nano-Technology (IEMENTech), 2018
This paper proposes a new method of beamforming for colocated MIMO radar. The method firstly constructs the coprime arrays in MIMO radar and then exploits the minimum variance distortionless response (MVDR) to maximize the power in the desired direction and minimize in other directions.

Coprime Array Design with Minimum Lag Redundancy

ICASSP 2019 - 2019 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2019
In this paper, we propose a new sparse coprime array design that achieves a higher number of degrees-of-freedom for direction-of-arrival (DOA) estimation. The proposed array design completely avoids lag redundancies between the two constituting subarrays of the coprime array, thus achieving the maximum number of unique correlation lags under the ...

Sparse Direction-of-Arrival Estimation with Directive Coprime Arrays

2018 IEEE International Symposium on Antennas and Propagation & USNC/URSI National Radio Science Meeting, 2018
This paper proposes a sparse direction of arrival (DOA) estimation method for directive coprime arrays. The complex radiation patterns are extracted using an electromagnetic simulator and then incorporated in the DOA estimation. Three DOA algorithms are compared including Capon, MUSIC, and Lasso based on compressive sensing (CS).

Coprime array adaptive beamforming based on compressive sensing virtual array signal

2016 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2016
In this paper, we propose a novel adaptive beamforming algorithm for coprime array by compressive sensing the virtual uniform linear array signal. Based on the idea of coprime sampling, a much longer virtual uniform linear array can be generated from a coprime array. With a compressive sensing matrix, a connection can be built between the coprime array
