Abstract
A system and a method are provided for achieving long range, over the horizon (OTH), persistent surveillance, alerting, tracking and situational awareness against small, low radar cross section moving targets. The system and method use one or more tethered unmanned arial systems, or unmanned arial vehicles, to lift components including a radar antenna to a height above nearby obstacles or much higher. The system and method can also be used for subsurface radar detection and tracking applications, as well as communications with submarines.
