Testing of Doppler tolerant range sidelobe suppression in pulse compression meteorological radar

In radar meteorology, a technique has been devised for alleviating the Doppler sensitivity of sidelobe suppression so that the spectral moments of echoes from each range bin can be obtained with acceptably small flooding from neighboring range bins. The technique has been analyzed, but no pulse compression data from meteorological radar are available. The data available consist of zero-th, first, and second moments of radar echoes, from simple pulse radars. These data are used to produce simulated radar echoes from dispersed transmitted pulses by creating an appropriate complex envelope Gaussian process in each range bin. The effect of a dispersed pulse is obtained by properly combining the random processes over the appropriate number of range bins. The testbed so created can be used for a variety of signal processing techniques in radar meteorology. Using moment data supplied by the National Center for Atmospheric Research (NCAR), the radar echoes from dispersed pulses are simulated, and the authors´ Doppler tolerant sidelobe technique is tested.
