A Jamming Suppression Algorithm for Array Antenna Based on IGA

This paper presented a nulling algorithm for array antenna based on Immune genetic algorithm, which can suppress jamming with DOA different from signals effectively. The algorithm combines the evolution function of traditional genetic with vaccine injecting and density mechanism in creatures immune procedure. The adjustment of antibodies is realized by the expected breed rate, also the convergence rate is improved by the injected vaccine. Simulation results show that the algorithm is efficient and robust.
