Abstract: The system or method reduces the significant degradation of quality in Radar mosaic products that are contaminated by non-meteorological returns. In regions covered by multiple radars, the inventive algorithms utilize an inventive set of coverage-based rules for comparing returns from different radars in order to identify and suppress non-meteorological returns.

Abstract: The present invention relates generally to a method and apparatus for temporarily reforming or deforming the lip portion of a resinous seal so that the seal may be readily installed in an intended application. The invention includes a method and apparatus that includes a fixed frame unit having two leg portions and a backbone portion, a slot in each position, an axle in each slot, and roller assemblies received over each axle, with adjustment means for each axle, the guide rollers being circumferentially spaced apart and the center or reforming roller being adjustable.

Abstract: Radar coverage maps having blockage, coverage and clutter features available for ease of interpretation are provided using terrain data to establish such features in data sets. The data sets provide a basis for the modified display. Multiple tilts of the radar scan may be represented. Multiple radar zones may be overlapped to provide a mosaic of a region showing areas of no coverage despite overlap.
