Abstract

A system and method for coherent detection for identification of scattered laser light in a detection region. The system may have an optical sensor that collects a raw optical signal. The optical signal may be mixed with a local oscillator signal to generate a mixed baseband signal. Various processing may be performed on the mixed baseband signal. The system may use the mixed baseband signal to detect whether or not scattered laser light is in the raw optical signal.
