Oboe: history and development

The paper describes the history and development of the Oboe bombing-guidance system, and its applications. Oboe is a ground-controlled system, and the ground based operators give instructions to the bomber crews. There are several different versions of the equipment, all operating on different wavebands. The paper gives the theory of the system, and the technique of its use in operation. The subsequent use of Oboe in Operation Trinity (a bombing raid on Brest Harbour in France) and the problems experienced (mainly due to interference from other navigational radar systems) are also described.
