THEORY OF OPERATION
Block Diagram:
+12VDC Input
The Directional Radar Unit (DRU III) transmits a radio
frequency of 24.125 Gigahertz, in accordance with
Federal Communications Commission regulations. When
the transmitted signal strikes a moving target, it returns at
a different frequency because there is relative motion
between the two objects (radar unit and target). Targets
approaching the radar will return an echo higher than the
transmitted frequency. Targets receding from the radar
will return a lower frequency echo.
