Quadcopter active phased antenna array

Abstract

Group use of unmanned aerial vehicles (UAVs) for various purposes allows obtaining many of advantages in various tasks solvation. New advantages of UAVs group use are due the difficulty of separate observation of the group members and, accordingly, the difficulties of tracking and target distribution; the inability to serve the entire large group with the number of participants exceeding the capacity of the information control system of the opposing side; the increase in the behavioral complexity of the UAV in solving various problems through the use of artificial intelligence; random change of the spatial position of individual UAVs within the group, preventing their detection and selection of virtually all types of information systems. The noted advantages of the UAVs groups are especially pronounced in the implementation of such a fundamentally new method for creating active antennas based on the use of a group of UAVs carrying antenna elements and therefore forming and use of temporary active phased antenna arrays (APAA) of large sizes based on multicopter for the implementation of long-range radar systems. In this regard, the purpose of the report is to present a variant of the algorithm for the formation of such an APAA. On the example of solving the task of maintaining an air object, the features of the operation of a radar with an APAA based on a group of UAVs are illustrated.
