Hence, LPI. Spread-spectrum, UWB, directed transmissions in the high microwave bands, and so on. Dunno how useful the latter are for portable equipment, though, or in the battlefield conditions.
Bear has a point; no matter how you spread or hop, you're an emitter. Shoot anything that radiates from 50 Mhz-IR.

Ultrabroadband is currently hard to triangulate, unless you're part of the network, where TOF mutual triangulation is part of service. You could triangulate ultrabroadband with an antenna array, but in real life the reflexion and multipath will make it difficult.
Micro-lite (aerobody) burst transmitters will solve the problem handily. On Thu, 26 Jul 2001, David Honig wrote:
