Application of the SZ Phase Code to Mitigate Range-Velocity Ambiguities in Weather Radars

摘要

In has been demonstrated through simulations that the SZ phase code method of mitigating range ambniguities has a performance that exceeds any other known phase-coding scheme. This paper describes an implementation of this code on a weather radar and compares its performance with that derived from simulations. Spectral data obtained from NCAR's S-Pol radar, which had its transmitted phase coded with the SZ(8/64) switching code, are presented to illustrate the steps in this method.
