Patent US 11,193,738

A drone defense system having a mast assembly with a telescoping mast is provided. The drone defense system includes a housing rotatably coupled to a top portion of the telescoping mast. The housing has a flying drone tracking system and a flying drone countermeasure system. The drone defense system includes a computer that communicates with the flying drone tracking system and the flying drone countermeasure system. The flying drone tracking system detects a flying drone within a predetermined distance from the housing and generates a detection signal in response to detecting the flying drone. The computer receives the detection signal and generates a first control signal in response to the detection signal. The flying drone countermeasure system transmits an RF jamming signal in response to the first control signal.
