Joint Estimation of 2D-DOA and Frequency Based on Space-Time Matrix and Conformal Array
Each element in the conformal array has a different pattern, which leads to the performance deterioration of the conventional high resolution direction-of-arrival (DOA) algorithms. In this paper, a joint frequency and two-dimension DOA (2D-DOA) estimation algorithm for conformal array are proposed. The delay correlation function is used to suppress noise. Both spatial and time sampling are util...
متن کاملMatrix sign algorithm for sinusoidal frequency and DOA estimation problems
Fast algorithms based on the matrix sign function are developed to estimate the signal and noise subspaces of the sample correlation matrices. These subspaces are then utilized to develop high resolution methods such as MUSIC and ESPRIT for sinusoidal frequency and direction of arrival (DOA) problems. The main feature of these algorithms is that they generate subspaces that are parameterized by...
متن کاملRobust and Computationally Efficient Signal-Dependent Method for Joint DOA and Frequency Estimation
The problem of joint direction of arrival (DOA) and frequency estimation is considered in this paper. A new method is proposed based on the signal-dependent multistage wiener filter (MWF). Compared with the classical subspace-based joint DOA and frequency estimators, the proposed method has two major advantages: (1) it provides a robust performance in the presence of colored noise; (2) it does ...
متن کاملA New Algorithm for Joint Range-DOA-Frequency Estimation of Near-Field Sources
This paper studies the joint estimation problem of ranges, DOAs, and frequencies of near-field narrowband sources and proposes a new computationally efficient algorithm, which employs a symmetric uniform linear array, uses eigenvalues together with the corresponding eigenvectors of two properly designed matrices to estimate signal parameters, and does not require searching for spectral peak or ...
متن کاملA Simplified Sub-Nyquist Receiver Architecture for Joint DOA and Frequency Estimation
Joint estimation of carrier frequency and direction of arrival (DOA) for multiple signals has been found in many practical applications such as Cognitive Radio (CR). However, Nyquist sampling mechanism is costly or implemented due to wide spectrum range. Taking advantage of sub-Nyquist sampling technology, some array receiver architectures are proposed to realize joint estimation of carrier fre...
