Beamforming in terrain scattered jamming

Terrain scattered jamming is a recent problem for mainly airborne radars with low sidelobe array antennas. Modern jammers with array antennas can analyse the terrain scattering scenario and adapt the jamming signals and beam patterns to enhance the jammer effectiveness. Reciprocity between the radar antenna and the jammer antenna via terrain scattering can be used to control both radar and jammer functions and to optimise performance. The effectiveness of both functions is analysed by simulations. (5 pages)
