The National Severe Storms Laboratory has modified the NOAA’s research and development radar to support evolutionary changes that will be made on the WSR-88D network over the next several years. The main modifications are: (a) capability to operate in a multiple pulse repetition mode, including staggered pulse repetition time (PRT), (b) control of the transmitted phase from pulse to pulse, (c) capability to transmit simultaneous horizontally and vertically polarized waves, and (d) oversampling of the in-phase and quadrature phase components. These features are independent of each other; hence, any one combination of these can operate on the radar. On top, there is the capability to collect time series data so that various enhancing schemes can be tested post facto. Such after-the-fact investigations provide significant insight and allow comparative tests to help guide our choice of the evolutionary path that will happen over the next few years. Examples of collected data and sample results of signal processing will be demonstrated.
