Analysis on Influences of Unmanned Sensorcraft Wing Deformation Parameters on Conformal Antenna

An unmanned sensorcraft often has its numerous antennas and sensor devices arranged in the structure space of its wings. If the wings deform, conformal antennas will be affected. The object of this study is an unconventional configuration scheme of integrating an unmanned sensorcraft platform and conformal antennas. The aspect ratio, sweepback of the wing and flight altitude and speed are selected as the parameters for analysis and calculated to understand the influences of parametric variation on wing deformation. On this basis, the influences of parametric variation on the deformation of conformal antennas are analyzed. The results show that the aspect ratio has a significant influence on the x and z directions of the antenna, that the sweepback has a great influence on the y direction of the antenna, and that the flight altitude and speed have a small influence on the antenna radiation pattern. These conclusions can provide data support for the sensor dynamic compensation technology of unmanned sensorcraft.
