The Pipsqueek radar is used to provide a microwave cone of protection
around the lidar beams. The microwave beam has much larger divergence
compared to the lidar beams and airborne objects are detected by the
radar before they can intercept the lidar beams. When radar echos are
detected, the laser is immediately turned off. This radar was built
for the Navy P3 and Leandre water vapor DIAL in the IHOP_2002 experiment.
Pipsqueek routinely sees echos from aircraft at all altitudes over our site.
For more information on Pipsqueek contact ATD's Grant Gray or Frank Pratte.
