Abstract
The paper considers a model of a spatiotemporal signal at the output of the flat antenna array and the characteristics of this signal in the frequency domain. The issues of the formation of a three-dimensional signal are discussed when the oscillation arrives at the elements of a flat antenna array, taking into account the geometric features of the process of registering a signal with a flat digital antenna array. Equations for determining the delays between signals on adjacent elements of an equidistant antenna array are obtained. It is shown that the position of the active region of the spectrum depends on the angle of arrival of the oscillation, which can be the basis for further processing of signals, for example, for their separation, included to fighting interference.
