Abstract
A method of compressing data in a weather radar system utilizes a compression system. Weather radar data associated with graphical images provided on a weather radar display is compressed for downloads or downlinks from the airplane or storage on the airplane. The weather radar data can be compressed from any part of the process. In one embodiment, spatial resolution of the data is decreased while data resolution is increased.
Claims9
A method of compressing data in an aircraft weather radar system, the method comprising:
- receiving an indication of an event in the aircraft weather radar system;
- compressing weather radar data associated with graphical images provided on a weather radar display, the weather radar data being in response to weather radar returns, the compressing forming compressed data;
- and
- storing the compressed data, wherein the compressing step utilizes an algorithm based upon an array of blocks, wherein the blocks each have an approximately equal area, wherein the array is representative of a span of radials.
A method of compressing data for a weather radar display system, the method comprising:
- receiving first data on an aircraft used to provide graphical images associated with graphical data to be displayed on a display of the weather radar system, the first data representing radar returns at areas or volumes, wherein the first data represents the graphical images actually displayed on the display;
- and
- grouping selected areas or volumes together and performing at least an averaging function on the aircraft to provide second data, the second data being compressed at a ratio of at least 2:1 when compared to the graphical data, wherein the second data is formed by taking an average of the data in each group and adding a value for standard deviation.
