Abstract
A radar includes fixed beam radar transmitter and receiver antennae that utilize mixed polarization to optimize the object detection field-of-view through an intervening plastic fascia. The transmitter antenna transmits radar energy with slant polarization, a first receiver antenna designed for short-range wide-angle object detection passes only horizontally polarized radar energy, and a second receiver antenna designed for long-range narrow-angle object detection passes only vertically polarized radar energy.
