It isn't my area, but I think you're on the right track. Most radar systems have already (for decades, AFAIK) separated the emitter from the control panel with at least a long cable, so when the emitter gets smoked, at least the operators are more likely to survive. The USAF & DARPA are already publicly working on aerially deployed drone swarms, and it would not surprise me in the slightest if a swarm of theater emitters was among the goals (but I've got no inside info to share).
