Active phased antenna arrays for long-range mobile radars based on quadcopters

Abstract

Strengthening the role of unmanned aerial vehicles (UAVs) for various purposes due to their group use allows obtaining a number of advantages in solving a wide class of tasks. At the same time, the new advantages of group use of UAVs are due to: 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 new task as the formation 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 paper is to present a variant of the algorithm for the formation and functioning of such a APAA. On the example of solving the task of maintaining an air object, the features of the operation of a radar with a APAA based on a group of UAVs are illustrated.
