ALMA Memo # 504

The CloudSat Radar and Implications for ALMA

ALMA North American Technical Advisory Committee (ANATAC)
submitted by Darrel Emerson (NRAO)

2004-08-23

Keywords: CloudSat, Satellite, Radar

CloudSat is a downward-looking 94 GHz satellite-borne radar, due for
launch in April 2005. The peak EIRP of the radar beam is some 4.109
watts, which is sufficient to damage ALMA receivers on the ground if
ALMA antennas and the orbiting radar ever look directly at each other.
Although the likelihood of this happening is very small, ALMA does need
to take some operational precautions to avoid receiver damage, and to
flag data that will be contaminated by radar interference.
