Generalized Design Approach for Fourth-Order Difference Co-Array

2018 International Conference on Radar (RADAR), 2018
This paper presents a generalized approach to design fourth-order non-uniform linear arrays (NLAs) by combining any two second-order NLAs (e.g. co-prime array (CA), nested array (NA)). This new-formed NLA could exactly achieve a large hole-free range in its fourth-order difference co-array. By establishing the relationship between the second-order NLAs

DOA estimation in MIMO radar with broken sensors by difference co-array processing

2015 IEEE 6th International Workshop on Computational Advances in Multi-Sensor Adaptive Processing (CAMSAP), 2015
We consider the problem of direction of arrival (DOA) estimation in multiple-input multiple-output (MIMO) radar taking into account a possibility that some sensors are broken. In this case, the DOA estimation suffers from performance degradation. Motivated by the fact that the MIMO structure and difference co-array (MIMO-DC) processing can be used ...

Pseudo-beam-Forming for Direction-of-Arrival Estimation with Difference Co-array of Co-prime Array

Circuits, Systems, and Signal Processing, 2018
This paper focuses on direction finding using a co-prime array from the view of a difference co-array. According to the corresponding relationship between the correlation lag and virtual element position of the difference co-array, from the correlation matrix of the co-prime array, the desired correlation units are extracted as single-snapshot data of ...

Augmented L-Shaped Nested Array Based on the Fourth-Order Difference Co-Array Concept

2018 IEEE 10th Sensor Array and Multichannel Signal Processing Workshop (SAM), 2018
This paper presents a new two dimentional(2D) sparse array called the augmented L-shaped nested array based on the concept of fourth-order difference co-array. By properly choosing the relative positions of two L-shaped nested arrays, one could obtain a virtual planar array containing a large-scale hole-free uniform rectangular co-array.
