Introduction to RVP10

RVP10 is the next generation of dedicated weather radar signal processors developed by Vaisala and the legacy Sigmet over 40 years of history.

The RVP10 generation brings many needed hardware features to make use of the emergence of the solid-state power amplifier (SSPA) evolution that is about to take over transmitter technology. These features include:

  • Dedicated support of multiple transmitters within a single radar system
  • Generation and streaming of multiple channels of IQ data over network
  • Multiple waveform definitions used in parallel or in sequence transmitted over more than one carrier frequency having pulse compression, phase and polarity modulation
  • Dynamic and adaptive receive filter coefficients for the generation of IQ
  • Increased stability of time synchronization resulting in more accurate data tagging of antenna location during transmission and improvements in phase coherency
  • More linear ZDR measurement over the entire dynamic range when compared to RVP900
