Weather radar system and method with fusion of multiple weather information sources
First Claim
1. A method of displaying an image representative of a weather condition near an aircraft, the method comprising:
- receiving weather data representative of the weather condition from a plurality of weather data sources, the weather data including location data for the weather condition;
mapping the weather data received from each source to a common locational reference frame based on the location data;
adjusting the weather data received from each source to a common hazard scale;
determining a hazard level associated with the weather condition for a reference point in the reference frame based on the adjusted weather data for each source; and
displaying the image representative of the weather condition near the aircraft based on the hazard level for the reference point;
wherein adjusting the weather data comprises adjusting a portion of the weather data received from a first source of the plurality of weather data sources based on a characteristic of the weather condition indicated by the weather data received from a second source of the plurality of weather data sources, and adjusting the weather data by retaining the shape of a curve defined by the portion of the weather data received from the first source.

Abstract
A method of displaying an image representative of a weather condition near an aircraft includes receiving weather data representative of the weather condition from a plurality of weather data sources. The weather data includes location data for the weather condition. The method also includes mapping the weather data received from each source to a common locational reference frame based on the location data, adjusting the weather data received from each source to a common hazard scale, determining a hazard level associated with the weather condition for a reference point in the reference frame based on the adjusted weather data for each source, and displaying the image representative of the weather condition near the aircraft based on the hazard level for the reference point.

14. An aircraft weather radar system, comprising:
-
a processor; and a non-transitory memory coupled to the processor and containing program instructions that, when executed, cause the processor to receive weather data representative of a weather condition from a plurality of weather data sources, the weather data including location data for the weather condition; map the weather data received from each source to a common locational reference frame based on the location data; determine a hazard level associated with the weather condition for a reference point in the reference frame based on the adjusted weather data for each source; evaluate a confidence level for the hazard level at the reference point; and display an image representative of the weather condition near the aircraft based on the confidence level for the hazard level at the reference point; wherein the program instructions are configured to cause the processor to adjust the weather data by retaining a shape of the weather condition defined by a portion of the weather data received from a first source of the plurality of weather data sources based on a characteristic indicated by the weather data received from a second source of the plurality of weather data sources. - View Dependent Claims (15, 16, 17)

18. A weather radar system, comprising:
-
a processor; and a non-transitory memory coupled to the processor and containing program instructions that, when executed, cause the processor to receive echo top data for a weather condition from first and second weather data sources; map the echo top data to a common reference frame; adjust the echo top data received from the first source based on the echo top data received from the second source; and generate an image representative of the weather condition based on the adjusted echo top data; wherein the program instructions are configured to cause the processor to adjust the echo top data by increasing values of a portion of the echo top data received from the first source based on a height of the weather condition indicated by the echo top data received from the second source; wherein the program instructions are configured to cause the processor to adjust the echo top data by retaining the shape of a curve defined by the portion of the echo top data received from the first source in the adjusted data. - View Dependent Claims (19, 20)
