Patent ID: 7692576

Claim:
A method of generating a radar image to be displayed by a radar system, said method including: receiving range data and azimuth data carried by a radar signal transmitted from a radar antenna in communication with the radar system, wherein the range data and the azimuth data represent the radar image as a plurality of azimuth segments that collectively form the radar image in a polar coordinate system; translating the range data and the azimuth data into abscissa data and ordinate data that represent the radar image in a Cartesian coordinate system; filtering noise from the radar image by: utilizing a return signal contribution reflected by a target from at least two immediately-adjacent azimuth segments to render a representation of the target in the radar image, selecting a highest pixel value from a plurality of different pixel values assigned to be displayed by a common pixel of a radar display to be displayed by the common pixel, or a combination of both utilizing the return signal contribution reflected by the target from the at least two immediately-adjacent azimuth segments and selecting the highest pixel value from the plurality of different pixel values assigned to the common pixel to render the representation of the target to be included as a portion of the radar image to be displayed; and generating the radar image including the target to be displayed by a display screen to an operator.
