Abstract

The practical design of the receiver circuitry for an ir surveillance system is considered. A design procedure for obtaining high signal detectability is presented and illustrated with an explicit example. Filtering circuitry is designed which takes into account the nonwhite noise of the detector cell and the first stage of amplification. The tradeoffs between signal detectability, accuracy, resolution, and background suppression are also discussed.
