- Latest radar technology uses reflections from radio and television stations
- Expanded mission spectrum in civil air traffic control and military aerial reconnaissance
Cassidian, the defence and security division of EADS, has developed what is known as "passive radar" that can locate even difficult-to-detect flying objects such as stealth aircraft and that itself is practically undetectable. In contrast to conventional radar, passive radar doesn't emit any radiation, but instead analyses radiation reflections from other emitters, such as radio and television stations, to detect objects.
"The principle of passive radar has been known for a long time," says Elmar Compans, Head uf Rqbqmhc & Nmeearxkxe Soxdral su Fltvrbzdl.
