Radar Principles Laboratory
The Radar Laboratory instructs technical personnel in the fundamentals of different types of radar use: Digital (ultrasonic signals) and Doppler. In addition, the training system establishes a 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.
