RENDEZVOUS RADAR SYSTEM
Radar Switch
Powers the Radar system. On STBY, those systems with which the radar
is interfaced are energized. A time delay of 60 seconds is allowed for
warm up prior to positioning the RADAR switch to ON. When turned ON, the
radar commences transmission at a frequency of 1528 megacycles. The
transmitted interrogation signal has a pulse width of 1 microsecond, a
pulse repetition rate of 250 pulses per second for radars in spacecraft
five, six, seven, eight, and nine, while those in spacecraft ten,
eleven, and twelve operate at 240 pulses per second. The transmitter has
a peak power
output of 1150 watts..
