    Abstract: A radar antenna assembly includes a microstrip patch, a hybrid coupler, a phase shifter, and a power divider. The microstrip patch is configured to emit a radar signal. The radar signal is characterized by a transmitted polarization of the radar signal. The transmitted polarization is influenced by a first transmit signal received at a first port of the microstrip patch and a second transmit signal received at a second port of the microstrip patch. The hybrid coupler is configured to orthogonally combine a first input signal and a second input signal to output the first transmit signal and the second transmit signal. The phase shifter is operable to vary the phase of the second input signal relative to the first input signal. The power divider is configured to divide unequally a source signal so the amplitudes of the first input signal and the second input signal are substantially equal.

    Abstract: An antenna suitable for use as a phased array antenna of a radar system. The antenna includes a plurality of radiating elements, and a substrate integrated waveguide (SIW) configured to form a feed network to couple energy from a plurality of inputs to the radiating elements. The feed network includes over-moded waveguide couplers configured so energy propagates through an over-moded section in multiple modes, TE10 and TE20 modes for example. The feed network also defines sub-arrays configured such that half of the radiators of a sub-group are shared with an adjacent sub-group of an adjacent sub-array, i.e. the sub-arrays are configured to have 50% overlap. Preferably, the feed-network is formed about a single layer of substrate material.

    Abstract: A ground vehicle radar system includes a windshield of the ground vehicle and a radar device installed behind the windshield. The windshield includes a metallization layer configured to inhibit propagation of infrared radiation through the windshield that also inhibits the propagation of radar signals. The metallization layer defines an opening in the metallization layer for radar signals emitted and detected by a radar device to pass through. An antenna of the radar device is installed behind the windshield and aligned with the opening. A lower portion of the antenna has a first field of view through the opening characterized as being directed horizontal toward a horizon forward of the vehicle. An upper portion of the antenna has a second field of view through the opening characterized as being directed downward toward an area of the ground forward of the vehicle.

    Abstract: A sensor module configured to be located behind a window of a vehicle to detect an object through the window and about the vehicle. The module includes a radar unit with an antenna and a controller. The antenna emits and/or receives a radar signal through the window with a selected or preferred polarization. The polarization determines a preferred angle of propagation of the radar signal through the window based on reflection characteristics of the window that vary with impingement angle and transmitted polarization. By varying the transmitted polarization vs. beam direction when a directional antenna is used, the signal propagating through the windshield can be maximized to enhance object detection over a range of signal directions. Also, by varying the transmitted polarization when an omnidirectional type antenna is used, the object can be ‘illuminated’ with variable intensity and detected with variable sensitivity.
