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.
