Acoustic Detectors of Aircraft


 

 

 

Introduction

These pages were culled from a "round-robin" email - if anyone can supply details of the "what, when and where" for each picture, they would be of more interest.

 

Note (March 2022): Some of these photographs are included in the site Rare Historical Photos - Aircraft detection before radar, 1917-1940, together with additional textual detail. The site also features some photographs which are not included below.
