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: One example discloses an adaptive lighting apparatus, comprising: a first input configured to receive a set of radar data; a lighting module configured to generate a visible illumination signal based on the set of radar data; and a first output configured to transmit the illumination signal. Another example discloses an article of manufacture including at least one non-transitory, tangible machine readable storage medium containing executable machine instructions for adaptive lighting, wherein the instructions comprise: receiving a set of radar data; generating a visible illumination signal based on the set of radar data; and transmitting the illumination signal.
