摘要：A millimeter wave object detection and location system is disclosed comprisinga source generating a millimeter wave signal which is divided into an illumination beam,directed onto a field of view, and a local oscillator portion, mixed with radiation reflectedfrom objects in the field of view. The mixing is performed in a staring array of
mixer/detector elements which need not be mechanically or electronically scanned togenerate signals responsive to the entire field of view. The detected signal from eachelement is directly responsive to a portion of the field of view. The oscillator signal ispreferably linearly polarized, and a polarizing grid is used to separate the local oscillatorsignal and illumination beam and direct them in a simple and efficient manner. A twistreflector may also be used to rotate the polarization of a portion of the beam to direct itonto the mixer/detector array for mixing with the received signal from the field of view.
Improved constructions of millimeter wave source and mixer/detector elements arealso disclosed, which greatly simplify construction of the device.
