A quick bit of research comes up with the following:

The Jaguar V and Jaguar U are field radio units that were used extensively in the first Gulf War. They are British made. They use a technique called 'frequency hopping spread spectrum' to transmit radio signals. Encryption is built into the system.

The number of potential keys is 10^22, which sounds astronomical but is easily deciphered by our NSA. It's possible the system even has a backdoor or key recovery mechanism that allows us to monitor.

The radio fingerprint of FHSS is very unique. I have intimate knowledge of this technology and while very good, it's not the most difficult to track and identify.

For the very curious: to visualize FHSS, pretend that a television station transmitted one second of a show on channel 1, then one second on channel 2, and so on. To see the show, you would have to change channels exactly in sync for things to make sense. The Jaguar systems do this up to 100 times per second. Then scramble the show in one of 10^22 different ways just to make things gamey. Sounds outrageous but again, this is softball stuff for us to monitor.

Just FYI! It seems like the administration must be pretty darn sure they got him if they're letting a specific piece of intelligence like this out in the open.

This has gone out so broadly to so many reporters that it is tantamount to an official announcement. Whatever the reason, it is clear the government wants it known that we targeted Saddam.

I'm actually surprised they still admitted it. No intelligence is more valuable than knowing your enemy has broken your encryption.
