Abstract
A control circuit for maintaining the sensitivity of an avalanche diode at an optimum is shown. Such diode, when used as a photosensitive detector in a receiver in an optical radar, is biased by the disclosed control circuit so that the frequency at which internally generated noise impulses are generated is maintained at a predetermined rate so that echo signals may be distinguished from such impulses.
