An enhanced expanding and shift sparse array based on the coprime array and nested array

open access: yesIET Radar, Sonar & Navigation
In recent years, sparse arrays based on the fourth‐order difference coarray (FODCA) have received increased research attention due to their small number of array elements and large consecutive virtual arrays.

Direction of Arrival Estimation Using Augmentation of Coprime Arrays

open access: yesInformation, 2018
Recently, direction of arrival (DOA) estimation premised on the sparse arrays interpolation approaches, such as co-prime arrays (CPA) and nested array, have attained extensive attention because of the effectiveness and capability of providing higher ...

Total Least Squares Method for Direction of Arrival Estimation [PDF]

open access: yesJisuanji gongcheng, 2019
In the Time Difference of Arrival(TDOA) positioning technology,when the position coordinates of the sensor have errors,the estimated value obtained by the Least Squares(LS) method no longer has the best unbiasedness,resulting in a decrease in the ...

Direction-of-arrival estimation for constant modulus signals

open access: yesIEEE Transactions on Signal Processing, 1999
In many cases where direction finding is of interest, the signals impinging on an antenna array are known to be phase modulated and, hence, to have a constant modulus (CM). This is a strong property; by itself, it is already sufficient for source separation and can be used to construct improved direction finding algorithms. We first derive the relevant

Acoustical Direction Finding with Time-Modulated Arrays

open access: yesSensors, 2016
Time-Modulated Linear Arrays (TMLAs) offer useful efficiency savings over conventional phased arrays when applied in parameter estimation applications. The present paper considers the application of TMLAs to acoustic systems and proposes an algorithm for

Fast estimation of array shape and direction of arrival using sparse Bayesian learning for manoeuvring towed line array

open access: yesIET Radar, Sonar & Navigation
The sparse Bayesian learning (SBL) algorithm has demonstrated its advantage in the direction of arrival (DOA) estimation. However, it requires a lot of computational cost to iteratively estimate the SBL hyperparameters from measurement data.
