The Radar Receiver is an instructional module designed to provide training in system- and module-level troubleshooting. It has switches that the instructor can use to insert faults. These switches, as well as the circuit boards and test points, are accessed through the hinged door on top of the module.

The Radar Receiver down-converts the received RF signal to baseband directly (homodyne receiver) for the three types of radar that can be implemented (CW, FM-CW, and pulse radars). Direct CW Doppler and FM-CW outputs are provided. Quadrature detection (I- and Q-channel outputs) is used for the pulse radar. Wideband amplifiers are used in the I- and Q-channels to ensure faithful baseband reproduction of the received RF signals.

Unregulated DC power is automatically supplied to the Radar Receiver through self-aligning connectors when it is installed on the Power Supply / Antenna Motor Driver.
