  • Marine bump map display
    Patent number: 7973705
    Abstract: A plotting system and method for plotting radar and/or sonar signals on a bump map, with a simulated height of each data point representing a corresponding signal strength. The plotting system may comprise a processing device for associating particular signal strengths with normal vectors. The normal vectors may be used to determine the simulated heights to be illustrated on the bump map. The plotting system may also comprise a display for graphically displaying the bump map. Furthermore, the processing device may also associate particular signal strengths with particular colors, such that both color and simulated height may illustrate the strength of the plotted signals.
