Paper Abstract

The article presents a short description of the methods of shielding terrestrial objects using land jammers. The necessary mathematical formulae needed to calculate the effectiveness of radar jamming to shield a single ground object for two variants are given: when the jammer is near to the shielded object and when it is away from it at a fixed distance. For the energy criterion, the method for calculating the sector of the ground object shield was presented, according to the parameters of the jammer, jammed airborne radar and aircraft flight altitude. The necessary mathematical relations have been given to determine the sector of the object's shield. The angular relations and distances between the object to be covered, the jammers and the attacking aircraft change during the raid. The results of numerical calculations illustrating the presented method for the exemplary parameters of the jammer station, the radar and the variant of the air raid are presented in the respective tables and diagram. The implementation of an effective object shield of the facility using land-based jammers depends mainly on the exact knowledge of the technical parameters of the jammed radars (the emitter database), the jammers, the distance between them and the attacking aircraft, the degradation coefficient used for calculations, the electromagnetic wave propagation conditions and the used jamming method. In order to achieve high effectiveness of on-board radars jamming, the software supporting the decision making process depends on the dynamically changing battle scenarios.
