The invention discloses a method, equipment and storage medium for rapidly predicting radiation characteristics of a radome, and belongs to the technical field of radar antennas. The method of the present invention is as follows: obtain a training data set, and each piece of training data includes state parameters and antenna radiation characteristics of antenna radiation; and normalize each piece of state parameter to obtain a training sample, and the sample of the training sample The label is the corresponding antenna radiation characteristics, so as to obtain the training sample set; based on the training sample set, the network parameter training is performed on the radiation characteristic prediction model based on the BP neural network; the current state parameters are obtained in real time, and input after normalization The radiation characteristic prediction model is used to obtain the prediction result of the antenna radiation characteristic. At the same time, the invention also discloses equipment and storage media corresponding to the method. The invention can realize the real-time prediction of the antenna radiation characteristics under the current antenna radiation state parameters, thereby providing accurate guidance information for the missile guidance control system in real time.
Description
technical field [0001] The invention belongs to the technical field of radar antennas, and in particular relates to a method, device and storage medium for quickly predicting radiation characteristics of a radome Background technique [0002] Radar-homing missiles are the main components of precision-guided weapons, in which the seeker realizes the search, identification and tracking of targets, and provides accurate guidance information for the missile guidance and control system. The radome is a device to protect the seeker radar antenna. As the speed and maneuverability of the missile are greatly improved, the radome must work in a harsher flight environment. The radome not only needs to meet the aerodynamic shape requirements of the missile, but also must have multiple functions such as wave penetration, high temperature resistance, impact resistance, ablation resistance, and rain erosion resistance. The most critical performance is that while the radome meets these req...
