In the case of mutual coupling the DOA (Direction of Arrival) and adaptive beam forming algorithms are analyzed. In practice the mutual coupling between the array elements can not be avoided. Thus the precision of DOA and beam forming performance are affected because of the change of array response vector aroused by the mutual coupling. The algorithms of DOA are deduced with the equivalent network...
A new decorrelation algorithm through perpendicular translation based on Uniform Circular Array (UCA) has been proposed in this paper. More than one covariance matrices were generated by shifting the array of received signal at two perpendicular directions firstly, and then a new covariance matrix which was a full rank matrix was obtained by averaging the previous matrixes and the signals mentioned...
In this paper, the effect of the mutual coupling compensation in an adaptive antenna linear array is considered discussed at the system of anti-jamming. Mutual coupling of antenna arrays and the compensation of the element stimulate voltages and the weight coefficients are analyzed via method of moment (MOM). The simulation results of 4 element and 8 element linear array digital beam forming (DBF)...
The smart antenna adaptive algorithms achieve the best weight vector for beam forming by iterative means. Whether the algorithm is good depends on the convergence rate and steady state error. Beam forming is directly determined by the two factors. The performance of the traditional LMS algorithm is analyzed in this paper. Then a new variable step size algorithm is proposed and is applied to beam forming...
