Delta-k-lidar sensing of the ocean surface.
A new lidar technique for detecting ocean surface waves is analyzed theoretically. The method is based on the Deltak-radar technique and detects the modulation of the low-frequency product of two frequency-separated backscattered laser fields. It is shown that this Deltak-lidar technique can have a much larger signal-to-noise ratio than Deltak-radar, primarily because of its ability to aperture average the speckle noise in the backscattered fields.
