| 1. A method for processing data related to weather phenomena in a meteorological radar system, the method comprising the steps
of:
receiving an echo signal from weather phenomena generated by transmitting a long pulse; and
employing a mismatched windowed filter on the echo signal such that the echo signal is compressed in time to achieve fine
range resolution without substantially degrading sensitivity and while achieving low range time side lobes for Doppler velocities
expected to be measured by the meteorological radar system.
