One proposed solution is to phase-code the transmitted signal, enabling the recovery of multiple trip data by re-cohering for the desired trip while suppressing the other trip echoes. Recovering data in both the first and second trips will double the range at a particular PRT, allowing use of short PRT values that provide large enough Nyquist intervals for useful velocity measurements while attaining the desired area coverage. In general, it possible to recover numerous trips. Taking full advantage of this technique requires spectral domain processing, which is not currently available on the WSR-88D radars. Phase-coded time series data has been collected from the KOUN testbed radar in Norman Oklahoma and the recovery technique has been evaluated off-line. This paper will present an overview of the phase coding techniques with emphasis on the processing filter notch width, the spectral reconstruction techniques and censoring of data not meeting some data quality criterion.
