Beampattern Synthesis with Linear Matrix Inequalities Using Minimal Array Sensors
By
Progress In Electromagnetics Research M, Vol. 9, 165-176, 2009
Abstract
A new beampattern synthesis formulation is proposed to compute the minimum number of array sensors required. In order to satisfy all the prescribed specifications of the beampattern, the proposed method imposes linear matrix inequality (LMI) constraints on the beampattern as developed by Davidson et al., which remove the need to discretize the beampattern region. As the proposed formulation is quasi-convex, an iterative procedure is used to decompose it into a systematic sequence of convex feasibility problems, in order to find the minimum number of sensors. The proposed method guarantees convergence if the globally optimal solution lies in the search interval, which is easily ensured at the start of the search.
