Antenna array synthesis with a minimum number of antenna elements is of interesting in many applications. In this work, a method based on regularized FOCUSS, for the design of sparse arrays is proposed. The proposed approach can give the locations and amplitudes of these sparse elements at the same time. Numerical simulations show the high accuracy of achieving the desired radiation pattern with maximally...
A novel algorithm based on propagator method (PM) and Eigenspace Beamformer (ESB) for robust adaptive beamforming is presented. It has robust characteristics under the conditions of finite samples, desired signal point error and high SNR environment. By using PM, the signal subspace can be derived by propagator matrix, which does not need the complicated eigenvalue decomposition (EVD) or singular-value...
Target localization system is one of the basic aspects for mobile robot navigation. One of the most popular navigation way is the navigation based on visual. But, this way is limited by the light and the field of view so that it can't accurately detect the targets in special environments. To resolve the above problem of target localization way based on visual, this paper has studied the sound source...
