And i was able to hear both, DEMON and LOFAR with the Flank Array.
DEMON stands for: DeModulationOfNoise and means the noise only from the prop of the target.
LOFAR means the lower frequences of the engines and gearboxes. With this tool you can analyse the number of cylinders of the engine, the number of turns per minute and the ratio of the gearbox. Very interesting stuff.
