Title Removal of spurious aircraft detections on weather radar
Abstract A weather radar detects and removes spurious
aircraft from a weather radar display by using one of the methods of
differentiating radar return length, estimating a vertical gradient of
reflectivity, tracking radar returns into regions that are eliminated from the
weather display to provide differentiation, tracking areas of radar returns
that allow detection and removal of the spurious aircraft in relative
geometries, differentiating Doppler velocity, and differentiating spectral
width. The methods may be used individually or in combination to improve
