Abstract In this paper, an improved beam optimization algorithm for spaceborne SAR applications is presented to reduce the number of optimizing variables and the calculation time, compared with the traditional algorithm. This algorithm improves on the traditional genetic algorithm. In order to reduce the number of the optimizing parameters and expedite the optimization speed, the coefficients of a group of orthogonal base functions are set as the optimizing variables. This algorithm has been widely used in many projects and results with high performance are obtained.
