Transmit And Receive Phased Array For Automotive Radar Improvement
US Patent:
2013008, Apr 11, 2013
Filed:
Oct 6, 2011
Appl. No.:
13/267546
Inventors:
Jae Seung Lee - Ann Arbor MI, US
Paul Donald Schmalenberg - Ann Arbor MI, US
Paul Donald Schmalenberg - Ann Arbor MI, US
Assignee:
Toyota Motor Engineering & Manufacturing North America, Inc. - Erlanger KY
International Classification:
H01Q 3/00
US Classification:
342372
Abstract:
Examples of the present invention include methods and apparatus for phased array automotive radar which allow reductions in erroneous detections such as sidelobe clutter and ghost images. An example radar includes a steerable transmit antenna and a steerable receive antenna. Transmit and receive beams may be steered using an electronic control circuit so the main lobe of the transmit beam remains generally aligned with the main lobe of the receive beam, and the side lobe of the receive beam remains generally aligned with a null in the transmit beam.
Calibration Method For Automotive Radar Using Phased Array
US Patent:
2013008, Apr 11, 2013
Filed:
Oct 6, 2011
Appl. No.:
13/267605
Inventors:
Jae Seung Lee - Ann Arbor MI, US

Paul Donald Schmalenberg - Ann Arbor MI, US
Assignee:
Toyota Motor Engineering & Manufacturing North America, Inc. - Erlanger KY
International Classification:
G01S 7/40
US Classification:
342174
Abstract:
Examples of the present invention include calibration methods for phased array radar apparatus. The calibration methods include an electronic calibration of phase shifters, and compensation for mechanical misalignment. Approaches are particularly useful for automotive radar, and may be used for initial calibration after installation on a factory line, or at later times such as at a service station whenever recalibration becomes necessary.

International Classification:
H01Q 3/00
US Classification:
342372
Abstract:
A microwave antenna system having a plurality of antenna elements arranged in an array having two spaced ends. A first phase shifter is electrically connected to a first group of at least two adjacent antenna elements at one end of the array to control the signal phase in that first group. Likewise, a second phase shifter is electrically connected to a second group of at least two adjacent array elements at the other end of the array to control the signal phase in the second group. Individual phase shifters are electrically connected to individual middle antenna elements for at least several of the middle antenna elements between the first and second groups.

Radar Field Of View Expansion With Phased Array Transceiver
US Patent:
2014002, Jan 23, 2014
Filed:
Jul 23, 2012
Appl. No.:
13/555864
Inventors:
Jae Seung Lee - Ann Arbor MI, US
Paul Donald Schmalenberg - Ann Arbor MI, US
Paul Donald Schmalenberg - Ann Arbor MI, US
Assignee:
Toyota Motor Engineering & Manufacturing North America, Inc. - Erlanger KY
International Classification:
G01S 13/93
US Classification:
342 70
Abstract:
Examples of the invention include radar apparatus having at least two phased array transmitters, each having a different elevation corresponding to heights of detected targets relative to the road surface. A low elevation transmit beam is directed at the road surface, and used to identify metal objects in the road surface, which often cause false detections in conventional devices but may not be actual collision hazards. A higher elevation transmitted beam is used to detect actual collision hazards to the vehicle.

Paul Donald Schmalenberg - Ann Arbor MI, US
Assignee:
Toyota Motor Engineering & Manufacturing North America, Inc. - Erlanger KY
International Classification:
H01Q 3/26
US Classification:
342374, 342372, 342375
Abstract:
A microwave antenna system having a plurality of antenna elements arranged in an array having two spaced ends. A phase shifter is electrically connected to a first group of at least two adjacent antenna elements at one end of the array and is also electrically connected to a second group of at least two adjacent antenna elements adjacent the other end of the array. Individual phase shifters are connected to individual middle antenna elements for at least several of the antenna elements between the first and second groups of antenna elements. A switch selectively electrically connects a phase delay line in series between the phase shifter and the second group of antenna array elements to effectively double the number of good beam positions of the antenna array.

International Classification:
H01Q 21/00
US Classification:
343893
Abstract:
An antenna with improved radiation efficiency is provided. The antenna includes an antenna array proximately coupled to a feed line. The antenna array includes a plurality of resonating lines. Each resonating line includes a plurality of axially aligned resonators. The resonators have a resonating surface. The resonating surfaces of the resonators at the ends of the resonating lines are larger than resonating surfaces of the resonators in the middle of the resonating lines. Power is supplied to each resonating ling through a feed line. Electrical field is uniformly distributed along the antenna array so as to improve the radiation efficiency of the antenna.

Paul Donald Schmalenberg - Ann Arbor MI, US
Assignee:
Toyota Motor Engineering & Manufacturing North America, Inc. - Erlanger KY
International Classification:
G01S 13/00, H01Q 3/00
US Classification:
342175, 342372
Abstract:
A radar apparatus includes a receiver having a plurality of receiver channels, each including an antenna element, a phase shifter, and a switch. The antenna element provides a signal that passes through a phase shifter to a switch. The signal may then be passed to a summing element if the switch is closed. The summing element receives signals from the receive channels, and provides a sum signal to a mixer. In phased array mode, the switches are closed and antenna controller adjusts the phase angles of the phase shifters. In DBF mode, the phase shifters are maintained at a set value, and switches are operated sequentially to provide time-multiplexed signals from the receive channels to the summing element.

A metamaterial microwave lens having an array of electronic inductive capacitive cells in which each cell has an electrically conductive pattern which corresponds to incident electromagnetic radiation as a resonator. At least one cell has a first and second electrical sections insulated from each other and each which section has at least two legs. A static capacitor is electrically connected between one leg of the first section of the cell and one leg of the second section of the cell. A MEMS device is electrically disposed between the other legs of the first and second sections of the cell. The MEMS device is movable between at least two positions in response to an electrical bias between the first and second sections of the cell to vary the index of refraction and resonant frequency of the cell.
