Elettronica Veneta
Radar Technology Laboratory

This Radar Laboratory is designed to study radar technologies and systems used in maritime navigation.
All devices are of professional type


Radar Technology Laboratory

It consists of a main Trainer unit and of various accessory units:

Radar Trainer (M702/EV)

  • Based on a modern and complete digital radar system, modified for the teaching of operation and installation of a radar system.
    Troubleshooting and servicing are also included.
  • This is the basic configuration of the program.
  • This Trainer consists of a large silk-screen printed panel,

    • Block diagrams, wiring diagram and test points
    • Components and circuits completely visible on the fore panel
    • Fault simulator
    • Radar indicator Unit
  • It is also provided with an outdoor unit, complete with support, that includes:
    • Slot Antenna and dummy load
    • Transmission and receiving circuits

μP Fault Simulator (M702-F/EV)

  • for microprocessorcontrolled fault control, via a keyboard and with a digital display

Interactive Software (SW-M702/EV)

  • for carrying out Lessons, Exercises and Troubleshooting with a PC

Electronic Compass (M702-C/EV)

  • That supplies information on navigation direction and North

GPS Receiver (M702-G/EV)

  • That applies information on geographic position

Radar Image Simulator (M702-T/EV)

  • That replaces the outdoor unit and supplies actual stored informations

Training Program:
