ABSTRACT:
A system for the distribution of digitized radar video over a digital network is presented. The digital network is located at the low data rate point in the radar scan conversion process resulting in low network bandwidth with no loss of video fidelity. The conversion from analog to digital distribution allows for a totally integrated information network eliminating the need for a dedicated radar distribution network. This approach broadens the use of radar data from traditionally dedicated consoles to all network users. The radar and display system architecture consists of one or more radars and displays. Each radar has a video digitizer and azimuth decoder that is coupled to receive radar analog signals representative of radar data in polar coordinates or other format, which are constructed to provide digital signals representative of said analog signals. Azimuth and range compressors are coupled to receive the decoded digital signals, which are constructed to provide range and azimuth data compression to the decoded digital signals. A window detector is coupled to receive the output of the compressors and is constructed to provide a window-detected output signal to conform to the display screen. The video signals are transferred to the display systems over a digital network, which is inserted between the output of the window detectors and the display systems. Each display system contains a video display configured for Cartesian coordinate display data and a scan converter, which converts digital data from the window detectors of selected radar processors from polar coordinate data format into Cartesian coordinate data format.
