US Patent 10482768 Vehicle function impairment detection

Systems, methods, and apparatuses are provided and include a receiver module that is configured to receive at least one radar signal. A control module includes a processor that is configured to execute instruction stored in a nontransitory memory. The control module is configured to generate a Fourier transformation based on the at least one radar signal, and the control module is configured to determine a presence of wave interference based on the Fourier transformation. A primary indicator module is configured to, in response to the control module determining the presence of wave interference, generate an indication. The indication corresponds to the presence of wave interference.
