RCAF Station Cranberry Portage
Royal Canadian Air Force Station Cranberry Portage (also RCAF Station Cranberry Portage) was a military installation located in Cranberry Portage, Manitoba. Located on Athapapuskow Lake, RCAF Cranberry Portage was one of eight Sector Control Stations (SCS 700) on the Mid-Canada Line system of early warning radar stations. Each SCS received signals from a series of unmanned doppler transmitters located approximately 50 km apart. In Cranberry Portage, radio wave signals were transmitted along the chain of stations to the SCS, then to RCAF Station North Bay by land line. The radar station achieved full strength in April 1957 and was supported by RCAF Station Winnipeg. The Mid-Canada Line operations ceased in January 1964 and RCAF Station Cranberry Portage was turned over by the Department of National Defence (Canada), Department of National Defence to the Government of Manitoba for civilian use. Civilian use The residential and other facilities were used by the Frontier ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mid-Canada Line
The Mid-Canada Line (MCL), also known as the McGill Fence, was a line of radar stations running east–west across the middle of Canada, used to provide early warning of a Soviet bomber attack on North America. It was built to supplement the Pinetree Line, which was located farther south. The majority of Mid-Canada Line stations were used only briefly from the late 1950s to the mid-1960s, as the attack threat changed from bombers to ICBMs. As the MCL was closed down, the early warning role passed almost entirely to the newer and more capable DEW Line farther north. The MCL was based on the bistatic radar principle, using separated transmitters and receivers. An aircraft flying anywhere between the stations would reflect some of the transmitted signal towards the receiver, where it would mix with the signal travelling directly from the transmitter. The mixing of the two signals produces a pattern that is very easy to detect using simple electronics. As the transmitter is not pul ...
