Standoff Range Improvement of Electro-Optical Television Guidance Systems

摘要

A technique for increasing the maximum range at which a target can be identified and acquired (standoff range) by a television electro-optical guidance system when used under hazy atmospheric conditions has been developed and flight-tested. The standoff range increase is obtained by extending and limiting the spectral response of the television camera to near infrared and incorporating electronic contrast enhancement to increase the target contrast. This method provides increased standoff range by factors from 2 to 4. (Author)
