Abstract
Apparatuses, methods, and systems for surveying a site are disclosed. One method includes transmitting, by a ground unit, wireless signals while a directionally adjustable beam-forming antenna of the ground unit changes a beam direction of the transmission of the wireless signals to N beam directions, wherein the directionally adjustable beam-forming antenna includes a known motion, receiving and measuring, by an elevated unit, a magnitude and phase of the wireless signals transmitted by the ground unit through the N beam directions, determining N complex receive power representations wherein each complex receive power representation includes the measured magnitude and phase of the received wireless signals corresponding with each of the N beam directions, and determining a receive power summation comprising performing a complex summation of the N complex receive power representations.
