Abstract

A novel space-borne antenna nulling method is presented on rejecting strong multi-interference from the ground and air. Immune Genetic Algorithm for searching for the multi-extremum of maximum likelihood function has been developed, which is based on injecting vaccine pick-up adaptively. GA has the capability of the whole searching and is not limited by the selection of initial parameter. And the Immune algorithm possesses the advantage of availing oneself of characteristic information. The proposed method, combining GA with the Immune algorithm, can converge at the global optimum quickly and offer high resolution null point. Simulation examples, based on the spot survey data, are shown to illustrate the effectiveness and robustness of the proposed algorithm.
