  This paper develops the use of Inter-pulse frequency diversity scheme for a
weather radar system. It establishes the performance of frequency diversity
technique comparing it with other inter-pulse schemes for weather radar
systems. Inter-pulse coding is widely used for second trip suppression or
cross-polarization isolation. Here, a new inter-pulse scheme is discussed
taking advantage of frequency diverse waveforms. The simulations and tests of
performance are evaluated keeping in mind NASA dual-frequency,
dual-polarization, Doppler radar (D3R). A new method is described to recover
velocity and spectral width due to incoherence in samples from change of
frequency pulse to pulse. This technique can recover the weather radar moments
over a much higher dynamic range of the other trip contamination as compared
with the popular systematic phase code, for second trip suppression and
retrieval.
