circulator; and two limiters. The time-gated, variable-gain amplifier increases the peak RF power transmitted. It
also maintains the average RF power transmitted to a level that allows the system to be operated safely in a
classroom laboratory. The circulator is used for simultaneous transmission and reception using the same
antenna. The limiters prevent saturation in the I and Q channels of the receiving section of the system (i.e., the
Radar Receiver and the Dual-Channel Sampler).

Phased Array Antenna
581966 (9612-00)
The Phased Array Antenna is specifically designed to be used
with the Radar Training System. It allows an horizontal sector to
be scanned (azimuthal scanning) without any antenna motion.
The antenna can be tilted 90° to demonstrate elevation
scanning. The Phased Array Antenna consists of a microwave
switch coupled to a Rotman lens and microstrip tapered slot
array antennas. A built-in circulator allows simultaneous
transmission and reception.
