Clementine Collection

This color image shows three perspectives of some interesting Bistatic Radar Doppler Image data created by the Clementine spacecraft and recorded at the DSN. The top view shows a "waterfall" plot of the Fourier-transformed raw data, in which the S-Band Carrier appears as the narrow diagonal line sloping down to the left. The lunar reflected radar signal is the rainbow-colored broad, diagonal band sloping down to the right. The middle view is a processed image that has been realigned using the S-Band Carrier as the left-hand border. In the bottom view, the Moon's south pole appears in the radar signal as the vertical dark blue band. Horizontal bands represent thermal noise, and are due to receiver gain changes at DSN during the data collection. This data is being analyzed for the possible presence of ice on the Moon.

A high resolution image is also available. Warning: This is a large image (1.5 Mbytes).
