1. A transceiver assembly for detecting objects, comprising:
- a reflector coupled to a housing, wherein the reflector moves to sweep a beam of radiation to detect the objects and to receive the beam as reflected from the objects; and
an antenna comprising a plurality of patches coupled to a common feed for generating the beam and for detecting the beam as reflected from the objects.

Abstract
An improved transceiver assembly for a vehicle for detecting potentially hazardous objects is disclosed. The transceiver assembly preferably comprises a patch array feed antenna having an array of a plurality of patches for generating a beam and for detecting the beam as reflected from the potential hazards. The antenna is formed in or on a housing which also contains a parabolic dish that moves to sweeps the beam of radiation towards the potential hazards outside of the vehicle. In a preferred embodiment, approximately 77 GHz radiation is generated from and detected by the antenna.
