Abstract

Systems and methods prepare ground-based supplemental weather radar information for integration with onboard weather radar information. An exemplary embodiment receives ground-based weather radar information from a ground-based weather radar station, the ground-based weather radar information referenced in a first coordinate system; generates supplemental weather radar information from the received ground-based weather radar information, wherein the supplemental weather radar information is referenced to a second coordinate system based upon at least latitude and longitude; and communicates the supplemental weather radar information, wherein the communicated supplemental weather radar information is integrated with weather radar information of an onboard weather radar system of an installation vehicle.

Claims

1. A method that prepares ground-based supplemental weather radar information for integration with onboard weather radar information, the method comprising:

receiving ground-based weather radar information from a ground-based weather radar station, the ground-based weather radar information referenced in a first coordinate system, wherein the first coordinate system is a polar coordinate system referenced to a location of the ground-based weather radar station;

converting the received ground-based weather radar information in the first coordinate system to ground-based weather radar information referenced in a second coordinate system, wherein the second coordinate system is different from the first coordinate system, and wherein the second coordinate system is based upon at least earth-based latitude and longitude;

generating supplemental weather radar information from the received ground-based weather radar information, wherein the supplemental weather radar information is referenced to the second coordinate system; and

communicating the supplemental weather radar information, wherein the communicated supplemental weather radar information is integrated with weather radar information of an onboard weather radar system of an installation vehicle.

2. The method of claim 1, wherein the second coordinate system includes altitude.

3. The method of claim 1, further comprising:

identifying a geographic region of interest to the installation vehicle; and

selecting supplemental weather radar information of interest within the identified geographic region of interest.

4. The method of claim 1, wherein a portion of the supplemental weather radar information is represented using a first bit word, and further comprising:

modifying the representation of the supplemental weather radar information from the first bit word to a second bit word, wherein the first bit word has a greater number of significant bits that the second bit word.

5. The method of claim 1, further comprising:

receiving a request for the supplemental weather radar information from the installation vehicle, wherein the supplemental weather radar information is communicated in response to receiving the request.

6. The method of claim 5, wherein the request includes information indicating a planned flight path of an aircraft, and further comprising:

identifying a geographic region of interest to the installation vehicle based upon the planned flight path; and

selecting supplemental weather radar information of interest within the identified geographic region of interest.

7. The method of claim 5, wherein the request includes information indicating at least one of a location, a heading and a velocity of the installation vehicle, and further comprising:

identifying a geographic region of interest to the installation vehicle based upon the at least one of the location, the heading, and the velocity; and

selecting supplemental weather radar information of interest within the identified geographic region of interest.

8. The method of claim 1, communicating the supplemental weather radar information comprises:

broadcasting the supplemental weather radar information over a wireless medium.

9. The method of claim 1, communicating the supplemental weather radar information comprises:

communicating the supplemental weather radar information over the Internet.

20. The method of claim 1, wherein the second coordinate system is based upon at least the latitude and longitude of the installation vehicle.

10. A system that prepares ground-based supplemental weather radar information for integration with onboard weather radar information, comprising:

a communication system interface that receives ground-based weather radar information from a ground-based weather radar station, the ground-based weather radar information referenced in a first coordinate system that is a polar coordinate system referenced to a location of the ground-based weather radar station;

a processing system coupled to the communication system interface, wherein the processing system is configured to convert the first coordinate system of the ground-based weather radar information to a second coordinate system different from the first coordinate system and based upon at least earth-based latitude and longitude, and wherein the processing system is configured to generate supplemental weather radar information from the received ground-based weather radar information referenced to the second coordinate system; and

a supplemental weather radar information communication system interface coupled to the processing system and configured to communicate the supplemental weather radar information, wherein the communicated supplemental weather radar information is integrated with weather radar information of an onboard weather radar system of an installation vehicle.

11. The system of claim 10, wherein the second coordinate system includes altitude.

12. The system of claim 10, wherein the processing system is configured to identify a geographic region of interest to the installation vehicle, and select supplemental weather radar information of interest within the identified geographic region of interest.

13. The system of claim 10, wherein a portion of the supplemental weather radar information is represented using a first bit word, and wherein the processing system is configured to modify a representation of the supplemental weather radar information from the first bit word to a second bit word, wherein the first bit word has a greater number of significant bits that the second bit word.

14. The system of claim 10, wherein the supplemental weather radar information communication system interface is configured to receive a request for the supplemental weather radar information from the installation vehicle, and wherein the supplemental weather radar information is communicated in response to receiving the request.

15. The system of claim 14, wherein the request includes information indicating a planned flight path of an aircraft, and wherein the processing system is configured to identify a geographic region of interest to the installation vehicle based upon the planned flight path, and wherein the processing system is configured to select supplemental weather radar information of interest within the identified geographic region of interest.

16. The system of claim 10, wherein the supplemental weather radar information is communicated over the Internet.

17. A method that integrates onboard weather radar information and ground-based supplemental weather radar information, the method comprising:

receiving a radar weather return from a weather radar system on board an installation vehicle;

receiving the supplemental weather radar information, wherein the supplemental weather radar information is generated from ground-based weather radar information received from at least one ground-based weather radar station, wherein the supplemental weather radar information is based of a polar coordinate system referenced to at least a latitude and longitude location of the ground-based weather radar station;

converting the received ground-based weather radar information in the polar coordinate system to ground-based weather radar information referenced in a second coordinate system, wherein the second coordinate system is different from the first coordinate system, and wherein the second coordinate system is based upon at least latitude and longitude of the installation vehicle; and

generating a radar image showing the weather radar return integrated with the supplemental weather radar information.

18. The method of claim 17, further comprising:

displaying the radar image on a display.

19. The method of claim 17, wherein the polar coordinate system of the supplemental weather radar information received from the ground-based weather radar station is further referenced to an altitude of the ground-based weather radar station.
