Performance of Civilian Air Traffic Control augmented by twin radars

This paper summarizes the newly emerged technical challenges of the Civilian Air Traffic Control (CATC) and gives solutions how to overcome recognized shortcomings, highlights problems and requirements related to drones maneuvering capabilities and their very low Radar Cross Section (RCS). The solution is to explore advantages of the twin radar concept such as increased detection range by 60%, increased, superior angular resolution of the radars and increased plot update frequency. Examples for the twin radar performance demonstration are based on VHF radar, which have unique capabilities such as exploitation of multipath and resonance frequency for drones. A few peculiarities of the new signal processing and target detection are introduced with the extended air traffic control and monitoring network structure and basic performances.
