A Low-Complexity Nyström-Based Algorithm for Array Subspace Estimation

Subspace-based methods rely on singular value decomposition (SVD) of the sample covariance matrix (SCM) to compute the array signal or noise subspace. For large array, triditional subspace-based algorithms inevitably lead to intensive computational complexity due to both calculating SCM and performing SVD of SCM. To circumvent this problem, a NyströmBased algorithm for array subspace estimation...

DOA estimation exploiting a uniform linear array with multiple co-prime frequencies

The co-prime array, which utilizes a co-prime pair of uniform linear sub-arrays, provides a systematical means for sparse array construction. By choosing two co-prime integers M and N , O(MN) co-array elements can be formed from only O(M +N) physical sensors. As such, a higher number of degrees-of-freedom (DOFs) is achieved, enabling direction-of-arrival (DOA) estimation of more targets than th...

A New Method of DOA Estimation for Uniform Antenna Array

A novel method of direction-of-arrival (DOA) estimation based on subarray beamforming for uniform circular arrays is proposed. In this method, the beamform manifold of uniform circular arrays is transformed via virtual structure, and then the virtual array is divided into two subarrrays. The target DOA is estimated from the phase shift between the reference signal and its phase-shifted version ...

2-D DOA Estimation of LFM Signals Based on Dechirping Algorithm and Uniform Circle Array

Based on Dechirping algorithm and uniform circle array (UCA), a new 2-D direction of arrival (DOA) estimation algorithm of linear frequency modulation (LFM) signals is proposed in this paper. The algorithm uses the thought of Dechirping and regards the signal to be estimated which is received by the reference sensor as the reference signal and proceeds the difference frequency treatment with th...
