S-264
S-264 was operating in UHF-Band fully coherent terminal area and en-route surveillance radar. It is a further development of the Marconi S-234.
Type S-264A is essentially the same equipment as Type S-264, but incorporates a multi-cavity, high power klystron based power amplifier wich increased the peak power from 50 kW to approximately 500 kW. Both versions use a staggered pulse repetition frequency. The radar provides a highly efficient and stable MTI due to crystal control througout. The antenna uses a single curved (cylindrical) parabolic reflector with off-set slotted linear waveguide radiator. The elevation beam was created by the help of the reflection from the ground.
The S-264 entered the service in the airport of London Heathrow in 1954. S-264 was delivered in several foreigen states. Some radar sets remained in service until 1990.
