Difference pattern synthesis using a particle swarm optimizer

In this paper a simple feeding network is proposed for monopulse radar systems with small number of elements. Mutual coupling effects are included in case of difference pattern. Optimization in the presence of mutual coupling is proposed based on particle swarm optimizer (PSO). A bandwidth comparison is presented between two sets of excitations (weights). It is shown that the weights obtained by the PSO technique were less frequency sensitive as compared to the conventional weights based on the Bayliss distribution.
