Method for improving genetic algorithm based on liquid crystal optical phased array rarefaction
ActiveCN119227783Areduce in quantityImprove efficiencyBiological modelsComplex mathematical operationsFast Fourier transformGenetics
The invention discloses a method for improving a genetic algorithm based on liquid crystal optical phased array rarefaction, which comprises the following steps of: firstly, constructing a liquid crystal optical phased array physical model, then setting optimization parameters and fitness functions of the genetic algorithm according to array characteristics, obtaining a far-field directional diagram by utilizing space fast Fourier transform, and screening the fitness functions to obtain a far-field directional diagram; and performing coding, crossing, variation, inheritance, decoding and array population updating operation on the array population after the fitness function screening, and finally obtaining a final optimization result according to iteration stopping conditions. According to the method, through the improved genetic algorithm applied to the liquid crystal optical phased array, the number of control units of the phased array with the same aperture is reduced, under the condition that the total number of the control units is limited, the size, the weight and the complexity of a system are not changed, the larger aperture of the liquid crystal optical phased array can be achieved, and the method has a good application prospect for grating lobe suppression of the liquid crystal optical phased array. The number of control units is reduced, the aperture is increased, and an algorithm which is high in efficiency and easy to implement is provided.
