Surveillance technology that’s as blind as a bat
It’s actually a myth that bats
have very poor eyesight. In fact, some species have very good eyesight.
But what really allows a bat to be so highly attuned to its
surroundings, able to safely navigate their way through forests, and be
aware of other objects and animals in their immediate environment is
highly sophisticated echolocation. This natural sonar allows bats to
‘see’ their environment even in complete darkness through the echoes
returned from their high-pitched shouts. In radar technology,
echolocation is used in a similar way to identify moving objects in low-
or no-light situations.
