AN/SPS-64

The AN/SPS-64(V)9 system combines high transmitter power, high pulse repetition rate, narrow antenna beam width, a sensitive receiver, and a digitally enhanced display to provide a bright, accurate, and clearly defined radar presentation. The system is capable of driving one or more AN/SPA-25 indicators, of providing a blanking signal to the AN/SLA-10, and of accepting standard gyro inputs. The IP-1282B indicator contains a 12-inch CRT display which, due to a unique signal processor, provides a bright, daylight viewing display. Indicator control functions provide for selectable range scales out to 64 nautical miles, fixed range rings for target range estimation, digital LED readouts of exact target range and bearing, and the ability to offset ownship's position on the display. With a gyro input, the indicator can provide true or relative bearing displays. The RT-1246A receiver/transmitter operates on a fixed frequency of 9375 MHz and has a peak power output of 20 KW. The linear array antenna can rotate at speeds up to 33 RPM, which provides a high degree of target resolution and allows target information to be updated every two seconds.
