“…For the purpose of analysis, we will express the total phase errors as one random variable that will appear in the signal as random phase shift. So the phase of the received signal at the output of each channel in the array will be shifted by the geometric phase of this channel and the phase error, where the geometric phase of each channel is related to the geometry of array elements and the direction of arrival of the received signal [3][4][5]. Figure 1 shows a single channel in a phased array receiver.…”

“…Phased array is recently used in the tracking system of an unmanned aerial vehicle (UAV) signal to obtain a high gain datalink between the UAV and ground station [1], where phased array has the ability to achieve high speed tracking and avoid the problems of mechanical movement of the antenna in traditional systems [2,3]. However, phased array is sensitive to phase errors caused by increased sources of noise in the phased array [4][5][6]. These phase errors will affect the coherency required to achieve the array factor.…”

“…Meteorological radar arrays must have very high isolation between vertical and horizontal polarization in order to distinguish between different types of precipitation. Calibrating errors enhances the polarization isolation [1,2].…”

“…Прогресс в развитии радиолокационных систем в значительной мере связан с разработкой и созданием радиолокаторов на основе активных фазированных антенных решеток (АФАР) [1][2][3]. Ключевыми элементами таких решеток являются приемопередающие модули (ППМ), количество которых, в зависимости от назначения локатора, может составлять от сотен до нескольких тысяч штук.…”
