Table 1 Information of some representative airborne weather radar
Radar | Country/company | Wavelength | Scan mode | Application |
|---|---|---|---|---|
ELDORA(ASTRATA) | USA and France | 3 cm (X-band) | Rotary scanning of two antennas (forward and backward) with an angle of 18.5° | Convective storm detection with high resolution |
WXR-2100 | Rockwell-Collins | 3.1 cm (X-band) | Emits two beams with slight offset in the vertical (pitch) direction | Detecting convective clouds that threaten aircraft safety |
CRS | Goddard Space Flight Center(NASA) | 3.2 mm (W-band) | Scanning with a two-axis gimbal hanger(airborne)RHI scanning(ground-based) | Cloud measurement, especially cirrus |
ACR | UMass and JPL(NASA) | 3 mm (W-band) | Detect vertically downwards or upwards | Weak precipitation and snowfall |
Spider | Japan | 3 mm (W-band) | Scanning in the direction of the track from − 40° to + 95° | Cloud measurement |
