New Weather Radar Techniques: Ready for Operational Use?

  • Walter L. Randeu

Summary

Relevant new weather radar techniques are reviewed with respect to their operation principles, expected benefits and acceptance for use in operational networks.

Dual-frequency and frequency-agile radars are found to be of little value for routine operation, and therefore might remain restricted to special applications, probably in the research domain.

Doppler weather radars are available off-the-shelf from all major manufacturers, and can already be found in several operational networks. Their value lies in the suppression of ground clutter and the measurement of precipitation particle velocities.

The improvement of precipitation intensity estimates and the liquid/solid-phase discrimination are benefits brought in by polarisation diversity radars. With today’s technology to be implemented without problems, these radars are just on the way to leave the researchdomain and to become accepted for routine operation.

The typical weather radar for installation during the 90ies should be a combination of Doppler and polarisation diversity. Other advanced systems, like electronically steered (multibeam) antennas, are expected as last step forward at the end of the next decade.
