Abstract

Coherent laser radar receivers often generate electronic signals having very wide information bandwidths. 50 MHz bandwidths are routine and 2 GHz bandwidths are not uncommon. Processing wide bandwidth data to remove noise and to extract the required information can exceed the practical limits of electronic techniques. This paper presents the results of the development of an optoelectronic signal processing system for a coherent laser radar system. The system can accommodate signals up to 500 MHz having a duration as short as 17 microseconds or as long as 143 milliseconds.
