Abstract
The study of echolocation systems in bats involves engineering in two distinct ways: the emitted signals are almost entirely ultrasonic, so that one is dependent on instruments for their detection, and the bats have refined their systems under evolutionary survival pressure so that they now use sophisticated principles. There are about 650 models, with at least 50 million years operational experience in short pulse, f.m. chirp or Doppler modes
