[0045] Technical scheme of the present invention: a kind of anti-jamming method based on smart antenna and neural network algorithm, it comprises the following steps:
[0046] (1) Using the smart antenna back frame as a model, deduce the smart antenna structure (such as figure 1 ) mathematical model architecture. And based on the artificial neural network, the smart antenna structure is designed, and the shape of the antenna structure is controlled by the telescopic effect to meet the precision requirements of the antenna reflection surface. Among them, the ANN deformation estimator is based on the output of the detection element to estimate the deformation that has occurred {W c} p×1 , and use these estimated values as the input of the ANN shape controller {W c} p×1 , through the actuator control voltage {Vc} q×1 The stretching effect under the action controls the deformation of the structure.
[0047] (2) According to the Hamiltonian principle and the constitutive ...
