Abstract

Abstract: The beamforming method based on mode decomposition is a kind of very good beamforming method for circular sensor arrays, in order to apply it to the broadband beamforming, An against white noise robust beamforming method was proposed to design an expect beam. The method designed the modal domain robust modal coefficient using the model decomposition method to generate different beam under the different mode circumstances, using second-order cone optimization algorithm gain more reasonable compromise than the other methods in the broadband beam performance, The platform of choice and operation of space were provided according to the demand for beam performance indicators for the designers. Computer simulation shows that this method can realize constant beamwidth beam figure, and has a better effect than traditional second-order cone constant beamwidth method. Experiments also verify the feasibility of this method.

Key words: modal decomposition, circular sensor array, broadband beam forming, robustness, second-order cone optimization
