Abstract

The invention discloses an all-weather monitoring method for phased array antenna array plane deformation. The method comprises the following steps: main factors for antenna array plane deformation are determined, each factor is dispersed in a certain range, simulation working conditions are determined after a standardized orthogonal table is consulted, an antenna array plane finite element model is built, simulation working conditions are simulated one by one, structure deformation of the antenna array plane in different working conditions can be obtained, the simulation model is verified and corrected via a array plane deformation measurement result in a typical environment, simulation data is used as sample data, a phased array antenna array plane deformation monitoring nerve network model is built, the network structure parameters are determined orderly, a nerve network is trained and tested, antenna array plane working condition data which is monitored in real time is brought into a monitoring model, antenna array plane deformation is calculated in real time, and all-weather real time monitoring of phased array antenna array plane deformation can be realized. A problem of phased array antenna array plane deformation monitoring can be effectively solved, the method can be widely applied to the field of large-scale radar antenna precision control, and the method is particularly suitable for engineering equipment having high requirements for precision in complex working environment.

Description

technical field [0001] The invention relates to an all-weather front deformation monitoring method in the technical field of radar structure simulation and precision control, in particular to a neural network-based all-weather monitoring method for phased array antenna front deformation. Background technique [0002] Phased Array Antenna (Phased Array Antenna) is a kind of electric scanning antenna, which is arranged in a certain order by tens of thousands of radiating elements, and each radiating element has a controllable phase shifter or a combination of phase shifter and The amplitude and phase adjuster composed of the attenuator, the direction of the antenna pattern is realized by controlling the non-mechanical movement of the antenna itself through the phase of each radiating element. Compared with conventional mechanical radar, it has the following characteristics: long detection distance, high efficiency; high reliability, convenient maintenance; flexible beam and be...
