Radar Principles Laboratory

The Radar Laboratory instructs technical personnel in the fundamentals of different types of radars: Digital (ultrasonic signals) and Doppler. In addition, the training system establishes solid maintenance knowledge and understanding of the theory behind radar operation. The lab consists of dual training systems, each addressing an essential element of the subject.
