Abstract

Heterodyne detection of laser radar signals is much more sensitive than other non-coherent method. The theory and technology of heterodyne detection are being well developed. In 1985, R. J. Keyes proposed the autodyne detection in a transmission-reception coherent laser radar system with a single-frequency laser.[1] Furhter theoretical and experimenatl efforts were made by D.U. Flukiger et al in visible region in 1987.[2] In 1989, Pi Mingjia proposed a new method of coherent laser radar detect ion, the two-frequency autodyne(TFAD) detection.[3]
