A Quasi-Adaptive Algorithm for Smart Arrays

Abstract

Based on the theorem of antenna array pattern product, proposed a quasi-adaptive algorithm for smart arrays . The formulas for calculating the weights of antenna array were given. Using these formulas to calculate the weights , the complicated operations such as counter-matrix aren't required. The computer simulation showed that this algorithm was simple , required less computation , and the simulative results exhibited that the corresponding antenna array had the pattern without sidelobe, so all the interferences outside the mainlobe can be inhibited and the mainlobe of the antenna array was narrower , can pointed to and tracked the direction of desired user easily, so its characteristics were close to those of an adaptive smart array while the algorithm was simple and required less computation, it can be realized more easily in practice.
