A robust broadband focused beam-forming algorithm based on combining focus transform and second-order cone programming is proposed. Firstly, the broadband signal is divided into multiple narrowband signals. Secondly, every narrowband signal is focused on the determined optimal focusing frequency using the optimal focusing matrix, in other words, the broadband problem will be converted to a narrowband problem. Finally, the second-order cone programming will be used in achieving narrowband beam-forming. Simulations demonstrate the effectiveness of this algorithm.
