Range and velocity ambiguity mitigation techniques for the WSR-88D weather radar

Dusan S. Zrnic Sebastian M. Torres
IEEE International IEEE International IEEE International Geoscience and Remote Sensing Symposium, 2004. IGARSS '04. Proceedings. 2004  
Keywords-Doppler weather radar; range and velocity ambiguity mitigation; systematic phase coding; staggered pulse repetition time I.  ...  Several mechanisms are currently provided to alleviate effects of range overlaid echoes and velocity aliasing in the Weather Surveillance Radar-1988 Doppler (WSR-88D).  ...  Various schemes have been proposed to mitigate the effects of ambiguities, but few have been tested and even fewer are available on operational Doppler weather radars.  ...
