A Channelization-Based DOA Estimation Method for Wideband Signals
In this paper, we propose a novel direction of arrival (DOA) estimation method for wideband signals with sensor arrays. The proposed method splits the wideband array output into multiple frequency sub-channels and estimates the signal parameters using a digital channelization receiver. Based on the output sub-channels, a channelization-based incoherent signal subspace method (Channelization-ISM...
متن کاملAn AR Model Based Robust DOA Estimation
This paper investigates the possibility estimating the direction of arrival (DOA) in a system identification perspective. The system is modeled as an autoregressive (AR) process and extended Kalman filter (EKF) is used to estimate the DOA, which forms a state of the augmented state vector of the EKF. The states generate the signals at a linearly phased array. Simulation results demonstrate the ...

متن کاملAn Improved DOA Estimation Algorithm Based on Wavelet Operator
In array signal processing, direction of arrival (DOA) estimation has typically play a key role. Its task is to find the directions impinging on an array antenna to increase the performance of the received signal. How to let DOA estimation methods are applicable to most environments, has become the key of technique implementation. The previous traditional algorithms can get superior performance...
متن کاملSimultaneous Doa Estimation Based on Kolmogorov's Theorem*
The design of a new architecture for signal processing, based on the Kolmogorov's Theorem, is addressed in this paper. This architecture is applied to solve the problem of source separation. Particularly. an adaptive algorithm is proposed to separate simultaneously all the unknown impinging sources on an aperture of sensors. The implemented framework is composed of two different stages: the fir...
