The optimization of various electrical properties of the radome is uniformly expressed as a form of nonlinear programming and solved by genetic algorithm (GA). The original analytical method (AM) was improved. Based on the preliminary design results of the improved AM method, the radial thickness distribution of the radome was coded and the relationship between the genetic code and the performance parameter of the radome was established. Taking the optimization of the radome ’s transmissivity as an example, the GA is explained in detail, and the related formulas are deduced. Through the design of three-dimensional tangent oval radome with multi-layer medium structure, the correctness and effectiveness of the method are verified.
