Is anyone using the EMANE jammer (https://github.com/adjacentlink/emane-jammer-simple) with directional antennas in a simulation? I've got a simple simulation using directional antennas and freespace propagation where 2 nodes are given a single GPS event, then don't move, just point at each other:
1 ---- 2 They come up fine, traffic passes and nothing really happens. I've tried to add a jammer at a different lat/long/alt with corresponding antenna steering events to get the azimuth / elevation pointed towards node 2 (using the formulas here: https://github.com/adjacentlink/emane/wiki/Computing-Antenna-Gain): 1 ---- 2 / J- Although the jammer is configured to use the same transmitting frequency at the same power as node 1, I see no effects on node 2 in terms of traffic loss. The only way I can get an effect is to move the Jammer to the exact lat/long/alt as node 1 and use the same antenna steering az/el as node 1. Of course, this is less than ideal if I want to add mobility to the scenario - the Jammer will have to track node 1. What am I doing wrong? Has anyone else had success with jamming directional antennas in freespace propagation? Cheers, Michael J.
