A Super-Fast, Carrier Quieted Telemetry System for Missile Impact Instrumentation

A fast-rising, carrier quieted telemetry system has been developed which measures, to one microsecond, the time between events during the sled test destruction of an impacting missile. Because of the short transmission range expected during sled tests, reliable carrier quieting of the receiver is obtained with transmitters of power outputs under 100 mw. High speed of response is obtainable by the use of rapid on-off keying of the carrier and the use of receivers and pulse amplifiers of sufficient bandwidth. The timing information from the missile is read from a digital chronograph instead of being obtained by analyzing taped information.
