General Electric Recognition Signal Systems
Abstract
The object of this test is to determine the suitability of the General Electric recognition signal. equipment as a secret homing system for aircraft. The receiver was installed in the Laboratory truck and its general performance noted. The truck was then driven to nearby points in Maryland and Virginia at distances of 1-3/16 to 4-1/2 miles, and bearings on the Laboratory were observed at ten such points. These were checkedwith true bearings. The receiver was then installed in the radio research plane at the Naval Air Station, Anacostia, D.C. and two test flights weremade. The signal was rendered unintelligible in flight by vibration micro-phonics and ignition interference. Recommendations were made that the receiver be redesigned to operate on a plane in flight, that the indicated bearing be correlated with direction of night so that a single instrument will give continuous indication of angle between direction of flight and direction of transmitter from plane, that the degree of ignition interference elimination possible at the receiver be determined, and that this Laboratory be advised as to the amount of additional shielding and bonding necessary on the test plane.
