Pre-Detection and Pre-Registration Averaging of Full Wave Signals in Airborne LiDAR Bathymetry
Remote SensingA well-known technique to enhance the signal to noise ratio (SNR) of repetitive signals is to average them. The coherent parts of the signal add up constructively while the incoherent parts are averaged out.
