Thermal-structural Coupled Deformation Analysis of MIMO Radar Antenna Array
Pages 216 - 219
Abstract
The MIMO radar antenna array will produce structural deformation under the action of heating and gravity. The structural deformation of the antenna array will cause great damage to the electrical performance of the antenna, such as increasing the sidelobe level and decreasing the antenna gain, widening the non-centralized lobe, decreasing the ability of receiving and receiving signals of the antenna, and so on. Network coverage reduction, etc. In this paper, ANSYS software is used to simulate the deformation of antenna array of coherent MIMO radar. The deformation and stress of antenna array from 0 to 90 degrees under rigid fixed conditions at temperatures of 20 degrees and 100 degrees are studied respectively. The results show that with the increase of the installation angle, the deformation of the front decreases, and the reduction speed is faster and faster. When the installation angle is less than 45 degrees, the stress decreases gradually and the velocity slows down with the increase of the angle. When the installation angle is greater than 45 degrees, the stress increases gradually and tends to increase rapidly.
