SACR (Scanning ARM Cloud Radar) is operating in the X, Ka or W-Band dual-frequency scanning microwave and millimeter-wave radars for remote sensing of clouds. Two types of systems were built: X/Ka-band and Ka/W-band.
The X-band transmitter uses a traveling wave tube (TWT) -amplifier (a 200 W Solid state Amplifier is also available). The Ka and W-band transmitters use an Extended Interaction Klystron (EIK) as power amplifier. The SACR employs dual polarization antennas, high power amplifiers, and digital pulse compression waveforms with compression ratios in excess of 50:1. The entire system is deployed on the roof of a customized 20-ft sea container.
