Mitigation of Range/Velocity Ambiguities

SZ(8/64) Phase Coding Technique

The performance of the SZ-2 technique was evaluated on real weather data. Time series data were recorded with the KOUN research radar and processed offline using a MATLAB-based WSR-88D Signal Processing Subsystem simulator.

Parameters used for data acquisition are given in the following table: 

The fields of reflectivity, velocity, and spectrum width are displayed for several events. Labels on the figures indicate the variable (Reflectivity, Velocity, or Spectrum Width), the waveform type (Long, Medium, or Short), the transmitted signal (PC=Phase Coded or Non PC), the elevation angle (EL), the date, and the approximate time. The following selected case studies are available:
