ELDORA

ELDORA (Electra Doppler Radar) is an airborne, dual beam, meteorological research radar developed jointly at the National Center for Atmospheric Research (NCAR), USA and the Centre de Recherches en Physique de L'Environnement Terrestre et Planetaire (CRPE), France. ELDORA's first deployment was to TOGA COARE in the Solomon Islands in January and February 1993. ELDORA Characteristics: Number of Radars 2 (fore and aft) Wavelength 3.2 cm Transmit Frequency 9.3 - 9.8 GHz Beamwidth (circular) 1.8 ° Antenna Gain 38.7 dB Polarization (00 elevation) horizontal First Sidelobe Power -35 dB Beam Tilt Angle (fore and aft) ± 15-19 ° Antenna Rotation Rate 5-144 °/s Dwell Time 7-50 ms Rotational Sampling Rate 0.75-2.00 ° Peak Transmitted Power 40-45 kw Receiver Bandwidth 0.5 - 8.0 MHz Receiver Temperature (at antenna) <600 °K Pulse Repetition Frequency 2000-5000 Hz Minimum Detectable Signal (at 10 km) -12 dBZ Unambiguous Range 20 - 90 km Unambiguous Velocity (single PRT) ± 13 - 20 m/s Unambiguous Velocity (dual PRT) ± 80 - 100 m/s Number of Frequencies 5 Pulse Chip Length 0.25 - 3.00 µs Range Averaging 1-4 gates Total Cell Length 37.5 - 1200 m Along Track Beam Spacing 0.3 - 1.0 km Additional information available at "http://linus.atd.ucar.edu/rsf/eldora/eldora.html" [Summary provided by NCAR Atmospheric Technology Division] (en)
