CONSTRAINED OPTIMIZATION TECHNIQUE FOR GENERAL ARRAY PATTERN SYNTHESIS

A new technique for controlling the sidelobe level for general array p attern synthesis is presented. The basic idea is to introduce a weight ing function to the performance index based on the integral of the pow er response over the sidelobe regions. This Function more heavily weig hts the array power response further away from the mainlobe, so that i n the minimisation of the integral of the weighted power response over the sidelobe regions, very low sidelobes can be achieved. The resulti ng beam pattern is highly directional. Numerical results show that the proposed technique is very effective for general array geometry sidel obe control design.
