Abstract
A back-up aid indication system includes a sensor for providing detection coverage in a predetermined coverage zone behind a vehicle. The sensor includes a transmit antenna adapted for transmitting an RF signal having a quasi-collimated antenna pattern in a near field. The system further includes a waveform generator which selectively provides one of a frequency modulated continuous wave FMCW Chirp signal and a pulse waveform signal as the transmitted RF signal.
Claims32
A back-up aid indication system comprising:
- a sensor for providing detection coverage in a predetermined coverage zone adjacent to a vehicle, the sensor comprising a transmit antenna adapted for transmitting an RF signal having a quasi-collimated antenna pattern in a near field;
- and
- a waveform generator which selectively provides one of a frequency modulated continuous wave FMCW Chirp signal and a time domain pulse signal as the transmitted RF signal.
A-method for alerting an operator of a vehicle to the presence of a object comprising:
- selectively providing one of a FMCW Chirp signal and a time domain pulse signal;
- transmitting the selected signal;
- providing an antenna having a quasi-collimated antenna pattern in the near field;
- detecting the presence the object proximate to the vehicle;
- and
- providing an indication of the presence of the object to the operator of the vehicle.
An external vehicle antenna comprising:
- a housing disposed across a bumper fascia;
- a plurality of flexible waveguide channels disposed within the housing each having a pair of inner surfaces and a slot surface;
- and
- at least one coax probe coupled to at least one of the plurality of flexible waveguide channels.
