Over the last decade, the staggered PRT (pulse repetition time) technique has emerged as a viable candidate to address the mitigation of range and velocity ambiguities in the WSR-88D at intermediate elevations where ground clutter is not a major concern. This technique has been thoroughly analyzed through theoretical and simulation studies but had not been implemented on the WSR-88D until now. This paper describes a real-time implementation of staggered PRT sampling and processing on NSSLís WSR-88D research radar. The algorithm was tailored to allow a seamless insertion into the legacy signal processing pipeline and includes a simple map-based ground clutter filter. Operational tests show that the computational complexity of this method is well within the expected capabilities of the next generation ORDA (open radar data acquisition). Preliminary results included in this work demonstrate that the staggered PRT technique is a feasible candidate for mitigating range and velocity ambiguities in future enhancements of the national network of weather surveillance radars.
