SIMULATION OF MULTI-PATH DISTORTION OF A MODULATED CARRIER SIGNAL USING A MICROWAVE NETWORK
Abstract
Televisually guided air to surface weapons employ radio links to convey guidance pictures from the missile to the aircraft and command signals from the aircraft to the missile. The signals received via these links are subject to fading and distortion due to the simultaneous reception of signals transmitted by the direct path and signals reflected from the ground or other objects. A laboratory equipment has been designed to enable the effects of dual path propagation to be studied. Descriptions are given of the transmission paths and expressions derived to enable the parameters of the microwave simulator to be determined. The limitations of accurate simulation of multi- path propagation are examined and it is shown that the errors are small where the signal modulation bandwidth does not exceed 100 Mc/s.
