RELIABILITY RESEARCH

Abstract

The improvement of the reliability of IFF systems is being studied. This report is an investigation of the communication aspects of the ground-to- air IFF system. Factors affecting reliability are atmospherics, receiver noise, inadequate space resolution, garbling, and jamming and deception on the part of the enemy. The last factor was given prime consideration. Examples are given of the use of redundancy coding to improve the reliability of pulse-train transmissions in the presence of noise, but the method is rejected because of the complexity of the equipment required. A pulse-train correlator is being built which is designed for 8-place pulse trains using 0.6-usec. pulses spaced 3, 7, 6, 2, 12, 5, and 4 pulse widths apart. The use of a fixed directional airborne antenna and corridors is discussed.
