Improved pattern synthesis method with linearly constraint minimum variance criterion

For the pattern synthesis method of the arbitrary array antenna with the linearly constraint minimum variance criterion (LCMV-PS), the primary disadvantage is its poor adaptability, namely its performance is determined by the iterative coefficient. In order to improve its performance, the effect of the relative amplitude between synthesis pattern and its reference upon the pattern synthesis is considered adequately, via adding a proportion constant to the iterative formula, not only the pattern synthesis efficiency is improved, but also the adaptability is extended. By the novel improvement for its iterative coefficient, the application area and adaptability of the pattern synthesis method are enhanced. The last simulation attests its correctness and effectiveness.
