Modification of JM-1 Sono Buoy Equipment for Use in Torpedo Timing
Abstract
A method whereby standard JM-1 type Sono Radio Buoy equipment can be altered for use in automatically timing torpedoes over their test run is described in this report. By restricting the acoustic bandwidth of the equipment, using a directional hydrophone, and preventing limiting in the transmitter, the system was improved sufficiently to warrant its installation for use on the Naval Torpedo Testing Range, Piney Point Maryland.
