STRUCTURES FOR A VIDEO TELECOMMUNICATION SYSTEM OF A UAV(UNMANNED AERIAL VEHICLE) USING A WIBRO AND ADAPTIVE VERTICAL STATIC BEAM-FORMING ARRAY ANTENNA ALGORITHM TO OVERCOME RESTRICTION OF THE ALTITUDE FOR UAV, PARTICULARLY FOR FORMING A BEAM PATTERN ADAPTIVELY AT A LARGE ANGLE IN WHICH SIGNAL STRENGTH IS LARGE

摘要

PURPOSE: Structures for a video telecommunication system of a UAV(Unmanned Aerial Vehicle) using a WiBro and adaptive vertical static beam-forming array antenna algorithm to overcome restriction of the altitude for UAV are provided to estimate the arrival angle of the direction having high SNR(Signal to Ratio) by using an adaptive phase control algorithm.;CONSTITUTION: A WiBro is applied as a communication system of unmanned aerial vehicles, and information is received continuously at a remote place. The image transmission and reception system of the unmanned aerial vehicle to which the WiBro is applied transmits and receives image information to and from the image transmission and reception system. An array antenna is applied to an aerial vehicle, and the SNR is maximized as a high antenna gain at an aerial altitude where a signal of a base station cell coverage hardly influences.;COPYRIGHT KIPO 2010
