Here is a bit of information about an on going project in Australia. Most of you would have heard of Jindalee, the Joint Operational Radar Network
(JORN), but have you heard of its little brother?
Welcome to SECAR - Surface Wave Extended Coastal Area Radar.
This looks like a better method than the navy's low frequency sonar radar that seemed to interfere with the natural sonar of the dolphins and whales.
Possibly to the extent of them beaching themselves.
I've been here too long (ATS). When it seems too good to be true, it usually is!
