Abstract

Abstract:

By establishing a mathematical model for parameter optimization design of the missile-borne synthetic aperture radar (SAR), a parameter optimization design method for missile-borne SAR based on the genetic algorithm is proposed, which solves the problem of the system parameter optimization design for the missile-borne SAR under the condition of definite trajectory and multiple nonlinear constraints. This method can quickly obtain the system parameters which make the image performance optimal on the premise of meeting the requirements of the system indexes (resolution, width, data rate, noise equivalent backscatter coefficient, etc.). Meanwhile, this method is also applicable to the system parameter optimization design of multiple azimuth beam position modes. Simulation experiments based on the typical working parameters show the effectiveness of the proposed method.

Key words: missile-borne synthetic aperture radar (SAR), parameter design, genetic algorithm (GA), nonlinear constraint, multiple azimuth beam position
