Patent ID: 7268725

Claim:
A method to display coordinates of radar scan data comprising: dividing an angular display interval into at least one sweep sector; computing polar (r, θ) coordinates for rectangular (x, y) coordinates at each pixel of the angular display interval; computing bounds and angular width of a block of polar radar (R, Θ) coordinates that map to a given pixel of the rectangular (x, y) coordinates; creating a mechanism to associate the bounds of the block in polar radar (R, Θ) coordinates with the rectangular (x, y) coordinates; calculating bounds associated with an x-coordinate of the given pixel in a first sweep sector of the at least one sweep sector; assigning a maximum of the calculated x-coordinate bounds to x max and a minimum to x min ; calculating bounds associated with a y-coordinate of the given pixel for each x-coordinate in the first sweep sector; assigning a maximum of the calculated bounds of the y-coordinate to y max and a minimum to y min ; retrieving the bounds and the angular width of the block of polar radar (R, Θ) coordinates for each rectangular (x, y) coordinate from the mechanism; retrieving observed radar parameter values scanned within the corresponding retrieved block bounds; and displaying the parameter values within the block on a display.
