Early Radar Usage

Early Radar Usage

American troops using a newly-developed acoustic locator, mounted on a wheeled platform. The large horns amplified distant sounds, monitored through headphones worn by a crew member, who could direct the platform to move and pinpoint distant enemy aircraft. Development of passive acoustic location accelerated during WWI, later surpassed by the development of radar in the 1940s.
