ST50 PLUS RADAR Operation and Installation Handbook
The compact design of the display unit is made possible by the use of
custom LSI (Large Scale Integrated circuit) components. An LSI type
of "chip" contains, in one package, the equivalent of up to 30
integrated circuits. Thus compact size, power efficiency, and full
radar navigation features at an economical price are all "standard" in
the ST50 radar system.

1.2.2 Radome Antenna Unit Main Features

The antenna and transceiver are contained within the 18 inch radome
assembly, the radome is made of AES plastic and has a single-flange
mounting. The radome protects the electronic assemblies from the
environment, yet is transparent to the radar's RF energy, thereby
allowing full performance. A small, flexible interunit cable connects the
Radome Unit to the Display Unit.
The radome cover is secured to the pan base by four clamping bolts
and is provided with a heavyduty rubber
unit from the weather and salt spray.
Inside, the radome features a printed-circuitcard array. This technically
innovative antenna provides a narrow 6' beamwidth for excellent short
range resolution and high gain in a very compact antenna package.
The internal X-band transmitter operates at
a sensitive micro-integrated circuit (mic) front end receiver.
The construction of the antenna unit is modularized, so repairs, should
they be required, can be made quickly and cost-effectively.
