Abstract
In order to increase the capacity of communication link between ground and planetary spacecraft, antenna arraying technology is adopted in deep space communication. For antenna arrays construction, array elements geometric configuration optimizing is a key technology to improve array performance. Firstly, calculation method of instantaneous synthesized beams is presented, and an optimization model of array for a given tracking direction is built. Secondly, For limitation of standard genetic algorithms, an improved genetic algorithm (IGA) for array configuration optimizing is given. Finally, Base on IGA optimization algorithms and Pareto multi-objective genetic algorithms, multi-objective array configurations optimization is carried out between minimum side lobe level and cable length, and between minimum side lobe level and main lobe width.
