Abstract
The report presents a review of the requirements and methods for technically effective communications jamming. An equation to determine technical jamming effectiveness is introduced. The equation allows calculation of the jammer-to-signal (J/S) ratio at the target receiver. The equation requires knowledge of the jammer power and the power of the target transmitter, the antenna gains over the jammer-receiver link and the transmitter-receiver link, and the path loss between the jammer and receiver and the transmitter and receiver. There is an overview of the methods to determine path loss. If the J/S ratio required to jam a link is calculated, the technical effectiveness of a particular jamming scenario can be determined because thresholds of J/S ratio required for jamming are tabulated. An overview of the types of communications electronic counter-measures, their implementations, and their problems is also included. Both jamming and deception techniques are discussed.
