چکیده
In order to flexibly and completely suppress dynamic interference, a flexible robust beamforming based on JADE is proposed in this paper. addition, it insensitive the gain–phase errors of array. Firstly, actual steering vector with separated from received snapshot data by joint approximate diagonalization eigenmatrix (JADE) algorithm. Secondly, direction arrival (DOA) interference can be estimated correlation coefficient method. Thus, selected nominal constructed DOA. Then, covariance matrix reconstructed vector, power Capon spectral. Finally, according prior information only tapered novel trap (CMT), which broaden deepen null. Simulation results show that depth beamformer more than 10 dB deeper traditional algorithm non-stationary interference. save at least 2 degrees freedom compared

Null broadening adaptive beamforming based on covariance matrix reconstruction and similarity constraint
In this paper, a procedure for the null broadening algorithm design with respect to the nonstationary interference is proposed. In contrast to previous works, we first impose nulls toward the regions of the nonstationary interference based on the reconstruction of the interference-plus-noise covariance matrix. Additionally, in order to provide a restriction on the shape of the beam pattern, a s...
متن کاملModified Null Broadening Adaptive Beamforming: A Constrained Optimisation Approach
A constrained optimisation approach for null broadening adaptive beamforming is proposed. This approach improves the robustness of the traditional MVDR beamformer by broadening nulls for interference direction and the mainlobe for the desired direction. This optimisation is efficiently solved by semidefinite programming. The proposed approach, when applied to high altitude platform (HAP) commun...
متن کاملNull-broadening in a waveguide.
Null-broadening, introduced in plane wave beamforming, is extended to an ocean waveguide in the context of matched field processing. The method is based on the minimum variance processor with white noise constraint and the distribution of fictitious sources using the theory of waveguide invariants. The proposed method is demonstrated in simulation as well as with data collected during the SWell...

متن کاملNear Optimal Robust Adaptive Beamforming Approach Based on Evolutionary Algorithm
The presence of desired signal in the training data for sample covariance matrix calculation is known to lead to a substantial performance degradation, especially when the desired signal is the dominant signal in the training data. Together with the uncertainty in the look direction, most of the adaptive beamforming solutions are unable to approach the optimal performance. In this paper, we pro...
