Dealiasing Doppler Velocites Using Edge Detection
This study presents a new algorithm to dealias folded Doppler velocities in S, C, and X-Band radars using a new boundary detection technique on the raw velocity field as a whole, rather than the traditional gate by gate methodology used in more popular and widespread algorithms. Several different ty...

| Summary: | This study presents a new algorithm to dealias folded Doppler velocities in S, C, and X-Band radars using a new boundary detection technique on the raw velocity field as a whole, rather than the traditional gate by gate methodology used in more popular and widespread algorithms. Several different types of precipitation events are used to compare and contrast the final output of the new boundary based algorithm. The results are then compared to the NEXRAD dealiasing algorithm as defined by Eilts and Smith (1989) and an objective manual unfolding by radar manipulation software called SoloII. === A Thesis submitted to the Department of Earth, Ocean, and Atmospheric Science in partial fulfillment of the requirements for the degree of Master of
