An Improved Adaptive Received Beamforming for Nested Frequency Offset and Nested Array FDA-MIMO Radar [PDF]
Sensors, 2018 For the conventional FDA-MIMO (frequency diversity array multiple-input-multiple-output) Radar with uniform frequency offset and uniform linear array, the DOFs (degrees of freedom) of the adaptive beamformer are limited by the number of elements.

Hole-Free Nested Array with Three Sub-ULAs for Direction of Arrival Estimation [PDF]
Sensors, 2023 Sparse arrays are of deep concern due to their ability to identify more sources than the number of sensors, among which the hole-free difference co-array (DCA) with large degrees of freedom (DOFs) is a topic worth discussing.

Distributed Super Nested Arrays: Reduce the Mutual Coupling between Array Antennas
International Journal of Antennas and Propagation, 2021 In array, mutual coupling between the antennas is inevitable, which has an adverse effect on the estimation of parameters. To reduce the mutual coupling between the antennas of distributed nested arrays, this paper proposes a new array called the ...

A New Nested Array Configuration With Increased Degrees of Freedom
IEEE Access, 2018 In this paper, a new linear array configuration based on the concept of two-level nested array is proposed. Specifically, the proposed array configuration consists of two uniform linear arrays (ULAs) plus a separate sensor with appropriate spacing apart.

A Novel Generalized Nested Array MIMO Radar for DOA Estimation with Increased Degrees of Freedom and Low Mutual Coupling [PDF]
SensorsIn array signal processing, the mutual coupling among physical sensors can inevitably affect the estimation of the direction of arrival (DOA). Despite the fact that multiple-input and multiple-output (MIMO) radar can provide greater degrees of freedom ...
