RTAWS active tower hazard detection system
First Claim
1. In an aircraft, including a weather radar system and a directional radio frequency receiver system and a display, and obstacle detection system for coupling to the display comprising:
- an interface for coupling to the radar system; and
a processor configured to determine a presence of a radio, television, or cell phone tower based on information received from the directional receiver, and the processor configured to cause the display to provide a representation of the tower, wherein the processor is configured to provide a warning of a presence of the tower in response to the tower being within an envelope of the weather radar system and being within a first distance from the aircraft, wherein the directional receiver is a broadband receiver.

Abstract
A system and method for a terrain awareness warning system. The system includes a radar system configured to transmit a first radio frequency wave and receive a second radio frequency wave, a display for receiving a display signal representative of an obstacle source and an obstacle source data circuit. The obstacle source data circuit includes an interface and a display circuit. The interface is coupled to the radar system and the display. The display circuit is configured to determine the obstacle source based on the second radio frequency wave and to transmit the display signal representative of the obstacle source.

10. A terrain awareness warning system for use on-board an aircraft, comprising:
-
means for receiving a reflected radio frequency wave associated with a target, the target being at least partially reflective, the target including a radio, cell phone, or television tower providing an active emission; means for receiving the active emission from the tower to detect the tower; means for determining a location of the tower based upon information from the means for receiving a reflected radio frequency wave; and means for generating a warning based upon selection criteria. - View Dependent Claims (11, 12, 13, 14, 15)

16. A terrain awareness warning system comprising:
-
a processor coupled to an obstacle data base for passively determining the presence of an obstacle, the obstacle including a radio, television, or cell phone tower, the radio, television or cell phone tower providing radio frequency emissions; a directional broadband receiver configured to detect the presence of the tower from the radio frequency emissions from the tower and coupled to the processor; and an active radar system configured to determine the presence of the tower based upon the reception of reflected radar signals, wherein the processor is configured to provide a warning signal in response to a distance to the tower and the tower being in an envelope of the active radar system. - View Dependent Claims (17, 18, 19, 20, 21)
