MARINE BUMP MAP DISPLAY
First Claim
1. A plotting system for displaying a marine bump map including a plurality of pixels, the system comprising:
- a display;
a memory operable to store data corresponding to at least one of a radar signal and a sonar signal; and
a processing device coupled with the display and memory, the processing device configured for;
determining at least one of a radar signal intensity and a sonar signal intensity corresponding to one or more of the pixels using the data stored within the memory;
determining a normal vector for a first one of the pixels, the normal vector being determined based on a signal intensity of the first pixel and signal intensities of one or more adjacent pixels;
determining a brightness value for the first pixel based on the normal vector and a light direction vector; and
commanding the display to present the first pixel as a portion of the bump map utilizing the determined brightness value.

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.
