1.4 Functional Description
The SRT 12 KW and 25 kW X-BAND Radar System is divided mainly into
Receiver and Transmitter sections, both connected to a solid state controlled
modular R.F. HEAD.
The Transmitter generates the R.F. energy in the X-Band range and pulses
modulated with a peak power of 12 or 25 kW. The length and PRF of the pulses
are in accordance with the range scale selected on the Display Unit. The
transmission pulses can be: Short, Medium and Long.
The Receiver enables reception of echoes and subsequent amplification in the
RF_Amplifier Assy.
The Electronics Rack unit also includes the circuits to generate the voltage
required for its operation.
The function of the Antenna unit is to:
1) Transmit the R.F: pulses within the specified (se b1.4.1) vertical and
horizontal lobes with horizontal polarization.
2) Receive the reflected R.F. echo signals and forward them towards the
RF HEAD.
