Abstract
An improved vehicle radar system and control aids the vehicle driver during both parking and back-up maneuvers. The radar system is equipped with both long range and short range radar detection antennas, an RF switch for selecting the active antenna, and a range bin having a depth that is adjustable “on the fly”. The back-up aid function is provided by activating the RF switch to select the long range antenna and setting the range bin to a relatively large depth to cover the long range in a short time. The parking aid function is provided by activating the RF switch to select the short range antenna, and setting the range bin to a relatively short depth to achieve high close range accuracy.
