Abstract
Examples disclosed herein relate to a radar system for use in millimeter wave applications. The radar system includes a lighting device, such as a light bulb or an array of light emitting diodes (LEDs). The radar system further includes an array of transmit elements to transmit at least one transmit signal, where at least one transmit signal reflects off of at least one object to generate at least one receive signal. The array of transmit elements is configured around at least a first portion of a perimeter of the lighting device. Also, the radar system includes an array of receive elements to receive at least one receive signal, where the array of receive elements is configured around at least a second portion of the perimeter of the lighting device.
Claims20
A method for operating an integrated radar system in a vehicle, the method comprising:
- transmitting at least one transmit signal via an array of transmit elements mounted around at least a first portion of a perimeter of a lighting device;
- reflecting the at least one transmit signal off of at least one object that generates at least one receive signal;
- receiving the at least one receive signal via an array of receive elements mounted around at least a second portion of the perimeter of the lighting device, wherein the array of receive elements are arranged orthogonally to the array of transmit elements;
- and
- implementing a set of receive guard antennas as side lobe filters, wherein a first receive guard antenna of the set of receive guard antennas is arranged at a first end of the array of receive elements and a second receive guard antenna of the set of receive guard antennas is arranged at a second end of the array of receive elements, the second end is opposite the first end.
A radar system, comprising:
- a lighting device;
- an array of transmit elements disposed on at least a first portion of a perimeter of the lighting device, wherein the array of transmit elements is configured to transmit at least one transmit signal;
- an array of receive elements disposed on at least a second portion of the perimeter of the lighting device, wherein the array of receive elements is configured to receive at least one receive signal generated by a reflection of the at least one transmit signal off of at least one object, wherein the array of receive elements is configured orthogonal to the array of transmit elements;
- and
- a set of receive guard antennas as side lobe filters, wherein a first receive guard antenna of the set of receive guard antennas is arranged at a first end of the array of receive elements and a second receive guard antenna of the set of receive guard antennas is arranged at a second end of the array of receive elements, the second end is opposite the first end.
An integrated radar system, comprising:
- a lighting device;
- and
- a radar system comprising:
- an array of transmit elements configured to transmit at least one transmit signal,
- an array of receive elements positioned orthogonal to the array of transmit element and configured to receive at least one receive signal generated from a reflection of the at least one transmit signal off of at least one object;
- and
- a set of receive guard antennas as side lobe filters, wherein a first receive guard antenna of the set of receive guard antennas is arranged at a first end of the array of receive elements and a second receive guard antenna of the set of receive guard antennas is arranged at a second end of the array of receive elements, the second end is opposite the first end.
