Abstract: In one example, a continuous-wave radar circuit receives reflection signals, computer processing circuitry processes data corresponding to the reflection signals, and emulation circuitry introduces a plurality of diagnostic data sets into the radar circuit to cause the radar circuit to process simulated reflection signals as though the simulated reflection signals are reflections from objects remote from the apparatus. The radar circuit may receive the reflection signals in response to chirp sequences actually transmitted as reflections from objects.

Abstract: A remote antenna system is provided. The remote antenna system comprises an antenna controller circuit and a remote antenna circuit coupled to the antenna controller circuit by a cable. The remote antenna system further comprises a bidirectional data signal path for carrying transmit and received data signals between the antenna controller circuit and the remote antenna circuit; and a control path for carrying control information between the antenna controller circuit and the remote antenna circuit. The control path is a bidirectional control path. The control path comprises a transmit circuit comprising an input to receive control information and configured to convert the control information into a series of pulses; and a receive circuit comprising a comparator circuit configure to receive the series of pulses and reconstruct them to the control signal.
