High Quality Content by WIKIPEDIA articles! Oboe was a British aerial blind bombing targeting system in World War II, based on radio transponder technology. The system went live in December 1942, about the same time as H2S radar was introduced.Oboe used two stations at different and well-separated locations in England to transmit a signal to a Mosquito Pathfinder bomber carrying a radio transponder. The transponder reflected the signals, which were then received by the two stations. The round-trip time of each signal gave the distance to the bomber. onder reflected the signals, which were then received by the two stations. The round-trip time of each signal gave the distance to the bomber. Each Oboe station used the radio ranging to define a circle of specific radius, with the intersection of the two circles pinpointing the target. The Mosquito flew along the circumference of the circle defined by one station, known as the 'Cat', and dropped its load (either bombs, or marking flares, depending on the mission) when it reached the intersection with the circle defined by another station, known as 'Mouse'.
