DOA estimation method based on Redundant Array Optimization: The algorithm of extending from monostatic nested array to bistatic nested array
Pages 1201 - 1206
Abstract
The traditional algorithm does not make full use of the redundant virtual elements in the same position of the "difference array", which still contain a lot of target parameter information. In this paper, a new processing algorithm is proposed. The redundant virtual elements in the same position are summated, and then the average value is calculated. The average value of the same element position is used to replace the original value of only one virtual element in the same position, so that a virtual received signal which makes full use of the virtual redundant elements can be obtained. Then the music algorithm is used to estimate the spatial spectrum to get DOA. Then, the algorithm is extended from single base nested array to double base nested array. The simulation results show that the algorithm is effective in two kinds of array structures.

DOA estimation in conformal arrays based on the nested array principles
The nested array structure has attracted great attention recently due to its ability in reducing the number of sensors in an array and at the same time preserving the array performance. While a uniform linear array (ULA) can detect at most N - 1 sources ...
Underdetermined DOA Estimation Algorithm Based on an Improved Nested Array
AbstractA nonuniform array group is proposed to solve the inflexibility problem of existing nested arrays. The array structure in the group is not required to be composed of two or more uniform linear sub-arrays on the premise of maintaining the same ...
2-D DOA estimation via correlation matrix reconstruction for nested L-shaped array
AbstractFor a nested L-shaped array (N-LsA) composed of two orthogonal nested subarrays, the self-difference co-array of each nested subarray is hole-free, whereas cross-difference co-arrays between subarrays have holes. Due to the existence ...
