摘要：

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