UNIT DESCRIPTIONS

RP-1 RADAR PROCESSOR

TR-1 TRANSMITTER/RECEIVER

DA-1A/B ANTENNA DRIVE WITH FP30-1 ANTENNA

D201002000008
Rev 1, December 2014
The Radar Processor contains the electronics
necessary to process the radar data received
from the transmitter/receiver, control the modes
of the radar and to format the radar data for
display. The RP-1 is normally located in the
avionics bay.
The Transmitter/Receiver contains the
electronics necessary to transmit, receive, and
process the radar pulses used to detect
turbulence, windshear, weather, and terrain
targets. It also contains the system integrity
monitoring and self test electronics. The TR-1 is
located in the radome in the base of the antenna
drive.
The component parts of the antenna drive are
the DA-1A (single) or DA-1B (dual) Antenna
Drive and the FP30-1 flat-plate array. The
antenna drive, located within the radome, forms
the microwave energy into a 3-degree beam.
The antenna also receives the return microwave
energy, after reflection by weather formations or
other objects, and routes these signals to the
transmitter/receiver for processing. The antenna
drive scans a 160-degree sector in azimuth and
±15 degrees in elevation (tilt).
