This paper introduces a family of alternating dual-pulse, dual-frequency (ADPDF) techniques. These are based on frequency diversity and are proposed as a means to mitigate range and velocity ambiguities on Doppler weather radars. ADPDF techniques are analyzed theoretically and through simulated and real weather data collected with a prototype C-band radar.(More)
The justification for the radars were based on several mandates other than the traditional use for severe weather. These include the use of radar for hydrology, climate applications, numerical weather prediction/data assimilation, environmental monitoring and commercial applications which include aviation. While weather radar have been used for these(More)
An intrinsic limitation of pulsed Doppler radars is given by the fact that range coverage and maximum unambiguous Doppler velocity are inversely coupled. That is, trying to improve one necessarily results in worsening the other, and trade-offs are often needed that hamper the observation of severe weather phenomena. Fortunately, significant strides have(More)
