Airborne antenna radiation was studied by hybrid Uniform geometrical theory of diffraction （UTD） and Optimization Algorithm. Matlab programs were developed to simulate the far field pattern of airborne antenna. Distributed Parallel Programs were designed to accelerate the running process, using the Matlab Distributed Computing Engine and the Matlab Distributed Computing Toolbox, together with computer network. Significant short running time proves that Distributed Parallel Programming can work in the simulation of large systems, Satisfactory far field pattern of airborne antenna was achieved, and analysis on the results was given.
