Abstract
A weather radar system includes processing electronics. The processing electronics sense weather and determine an uncertainty factor. A display can provide visual indicia of the uncertainty factor for weather in response to the processing electronics. The display can be a vertical profile display. The weather radar system can be an avionic weather radar system.
Claims20
A weather radar processing system for use with a radar antenna for receiving radar signals at a plurality of tilt angles, a tilt element for controlling the radar antenna, and a display, the weather radar processing system comprising:
- processing electronics configured to receive information from the antenna, the processing electronics configured to determine a height uncertainty and a hazard uncertainty, the processing electronics further configured to use the height uncertainty and the hazard uncertainty to determine an uncertainty factor for the weather;
- and the processing electronics are configured to cause the display to provide visual indicia of the uncertainty factor.
A method of displaying weather on a vertical profile screen of a display associated with an aircraft weather radar system configured to transmit and receive radar signals, the method comprising:
- processing the radar signals to determine a presence of weather;
- determining a height uncertainty associated with the weather;
- determining a hazard uncertainty associated with the weather;
- determining an uncertainty factor associated with the weather using the height uncertainty and the hazard uncertainty;
- and
- providing an indication of the uncertainty factor associated with the weather on the vertical profile screen.
An apparatus for displaying weather for an aircraft, the apparatus comprising:
- means for determining a presence of weather from weather radar returns;
- means for determining an uncertainty factor for the weather in response to the weather radar returns based upon a height uncertainty and a hazard uncertainty;
- and
- means for displaying indicia of the weather and the uncertainty factor, the uncertainty factor being displayed in plan view.
