Calculation of the Radar Coverage

for a Specific Image Area







Coverage calculations are calculated for only one path (depicted in red) segment.  Black is the entire radar path.  Blue is the outline of the image area





Coverage as a function of position within image area (shown in blue in the figure on the left)

   The other choice is the radar coverage as a function of Computational Increment (CI)  position within the image area.  First the radar positions that illuminate at least one CI are determined and grouped into continuous radar path segments.   Finally, the percentage of all the selected radar positions that illuminate each CI is also calculated.

   Variation of coverage is due to variations of roll, pitch and heading of aircraft, as shown here:
