ABSTRACT:
An angular scan interval may be divided into one or more sweep sectors for display. Polar (r, θ) coordinates may be calculated for rectangular (x, y) coordinates at each pixel of a display interval by computing polar (r, θ) coordinates in an interval of 0 to π/4 and by applying mapping equation sets. Bounds of a block of polar radar (, Θ) coordinates that map to a given (x, y) coordinate may be computed. A mechanism to associate the bounds of the block in polar radar (, Θ) coordinates and the rectangular (x, y) coordinates may be created. Bounds associated with the x-coordinate in a sweep sector may be calculated. A maximum of the x-coordinate bounds to xmaxand a minimum to xminmay be assigned accordingly. Bounds associated with the y-coordinate in the sweep sector may be calculated for each x-coordinate. A maximum of the bounds of the y-coordinate to ymaxand a minimum to yminmay be assigned accordingly. Bounds of the block of polar radar (, Θ) coordinates for each rectangular (x, y) coordinate computed from the mechanism may be retrieved. Radar observed parameter values scanned within the corresponding retrieved block bounds may be retrieved. Average or maximum parameter values within the block on the display may be displayed at the rectangular (x, y) coordinate.
