Abstract
Lidar backscatter from the plume of the third stage of the Red Tigress rocket was measured with the U.S. Naval Research Laboratory's laser ranging system integrated at the Air Force Optical Tracking Site in Malabar, Florida.1 To our knowledge these are the first calibrated Lidar measurements off a rocket plume throughout a trajectory. A block diagram of the system is shown in Fig. 1. The transmitter was a mode-locked Nd:YAG laser operating at 532 nm. The laser output is 300 mJ with a 250 ps pulse at a 10 Hz repetition rate. The laser was directed to the target through the 0.61 m telescope (T1) which projected a 70 grad beam as measured in the far field.
