In this paper, with the simulated signal data set obtained at the linear antenna array (ULA), the Long Short-Term Memory (LSTM) network model is used to estimate the DOA. The performance of the method is evaluated based on the RMSE parameter and compared with MUSIC, DNN algorithms in different cases such as: deviation of incident angle of radiation sources, signal-to-noise ratio (SNR).

In this paper, a feeding network based on Bat algorithm for pattern-nulling of a linear antenna array will be proposed. Bat algorithm has been used for calculating the amplitude of input weights for a uniform linear antenna array (ULA array) to place a wide null at a pre-defined position. A new feeding network structure to implement the excitation weights for a 12x1 ULA array will be proposed, designed and simulated.

In this paper, we propose an adaptive beamformer based on a binary bat algorithm (BBA) for pattern nulling of uniformly linear array (ULA) antennas. The optimized array pattern is obtained by controlling the phase of each array excitation weight.

This paper proposes a design of an adaptive beamformer for arbitrarily Uniformly spaced Linear Array (ULA) antennas. Least Mean Square (LMS), a prevalent adaptive beamforming algorithm, has been employed in the beamformer for the ULA antennas. A procedure has been introduced to validate the proposed design. Applying the proposal, a LMS based adaptive beamformer for 8×1 ULA antennas has been built and implemented on Xilinx FPGA.
