HENSOLDT NESIS 4000 - Friend or foe?

Leading the next generation of military IFF technology , NESIS 4000 is a non-rotating electronically steered antenna capitalizing on the latest AESA (Active Electronically Scanning Array) radar technology.
Using the AESA radar technology, NESIS 4000 radar beam can be steered electronically so that the system does not require a mechanically rotating antenna e.g. on top of the mast of the ship.
