Abstract
Abstract A radar system embeds information into the radar picture data for display on any display device. The radar receiver communicates weather data to a signal processor which generates a weather array. An I/O processor transmits data in the weather array to a display device via a picture bus. Alphanumeric data which is to be embedded into or combined with the weather array is stored in a message array. Font information for each alphanumeric character is stored in a font array. The message array and the font array are combined and translated into a text array which corresponds to the weather array. Prior to transmitting each radial of data to the display device, the I/O processor copies the appropriate radial data from the text array to the weather array thereby causing the desired alphanumeric characters to be displayed on the display device.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
123 words
A airborne weather radar system comprising: a) a data storage unit having, 1) a weather array containing data representative of weather phenomena detected by a radar receiver, 2) a message array containing alphanumeric data representative of alphanumeric characters to be displayed on an attached radar display device, and, 3) a font array containing bit map data representative of bit maps of said alphanumeric characters; and, b) an I/O processor in communication with said data storage unit, said I/O processor combining data in said message array and data in said font array to yield text data and combining said text data with the data in said weather array to yield radar picture data which is communicated to a display deviceusing a polar coordinate system.
Claim 2
Dependent Claim
123 words
A airborne weather radar system comprising: a) a data storage unit having, 1) a weather array containing data representative of weather phenomena detected by a radar receiver, 2) a message array containing alphanumeric data representative of alphanumeric characters to be displayed on an attached radar display device, and, 3) a font array containing bit map data representative of bit maps of said alphanumeric characters; and, b) an I/O processor in communication with said data storage unit, said I/O processor combining data in said message array and data in said font array to yield text data and combining said text data with the data in said weather array to yield radar picture data which is communicated to a display deviceusing a polar coordinate system.
Claim 3
Dependent Claim
36 words
