Array element position optimization method and device of unmanned aerial vehicle array antenna

The invention discloses an array element position optimization method and device for an unmanned aerial vehicle array antenna, and the method comprises the steps: obtaining an initial array element coordinate parameter of each array element, and determining the highest side lobe level of an array factor directional diagram of the unmanned aerial vehicle array antenna based on the initial array element coordinate parameter, the influence of the array element position on the highest sidelobe level is considered; and adjusting the initial array element coordinate parameter so as to perform minimum value optimization on the highest sidelobe level until the highest sidelobe level reaches a minimum value, and obtaining a target array element coordinate parameter of the array element, so that the highest sidelobe level is relatively low, and therefore, the array antenna has better environment anti-interference capability, and the stability of the array antenna is improved. And the influence of surrounding electromag
