1. 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.

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.
