Addressing the requirements for fast sidelobe stabilisation algorithms and their application in sonar signal processing

Adaptive beamforming (ABF) methods typically yield beam patterns that contain regions of high sidelobe gain. This can become a major problem when the platform is mobile with respect to noise sources. Real world ABF systems demand some sort of sidelobe control or stabilisation - one such approach is via penalty function methods. Computational speed is an important issue and their exists a requirement for computationally efficient methods of calculating penalty functions. One such method is described in this paper.
