INTERFERENCE PREDICTION GUIDELINES FOR VHF NON-TACTICAL FM COMMUNICATIONS

Abstract

The report presents guidelines which may be used for the prediction of interference effects between collocated VHF non-tactical FM equipments. Pertinent technical characteristics and interference susceptibility levels representative of this type of equipment are included. The interference mechanisms discussed include cochannel and adjacent channel effects and non- linear interactions due to spurious receiver responses, and transmitter and receiver intermodulation interference. Sample problems are set forth and solved to illustrate the step by step procedure for prediction of each type of interference phenomenon considered, and the equipment modifications required to prevent degradation.
