Doppler Lidar

•Long range (10-12 km)
•Fully scanning
•Extended velocity range

All-sky scanner with wipe facility. Azimuth slip-ring giving full hemispherical coverage with 0.01° resolution in both axes.
• Active heat exchanger. Temperature stabilised environmental enclosure. External temperature range -20°C to +45°C (active cooling option)
• System provides range gated line-of-sight velocity versus time
• System provides range gated SNR and backscatter
• Data collection to 12km with 100% duty cycle
• Raw averaged data can be stored (un-range gated)
• Gate overlapped mode
• Minimum range: Typically < 60m
• Pulse rate = 10 kHz
• Temporal resolution selectable in from 0.1 – 30 seconds
• Velocity precision < 20 cm s-1 for SNR > -17 dB
• Bandwidth: ±19m/s or (optional) ± 38m/s.
• Real-time display of data and system health checks
• Software selectable range gate size, number of shots to average and number of gates to process per ray
• Both step-stare and continuous scanning modes are possible. A daily schedule, synchronised to GPS time can be defined where the scan mode and scan parameters are set for each element of the scan sequence
• UDP data broadcasting
• Integrated GPS
