Abstract
A method (e.g., a method for measuring a separation distance to a target object) includes transmitting an electromagnetic first transmitted signal from a transmitting antenna toward a target object that is a separated from the transmitting antenna by a separation distance. The first transmitted signal includes a first transmit pattern representative of a first sequence of digital bits. The method also includes receiving a first echo of the first transmitted signal that is reflected off the target object, converting the first echo into a first digitized echo signal, and comparing a first receive pattern representative of a second sequence of digital bits to the first digitized echo signal to determine a time of flight of the first transmitted signal and the echo.
Claims20
A system, comprising:
- a time-of-flight (TOF) radar including a processing unit, a first transmit antenna coupled to the processing unit, a second transmit antenna coupled to the processing unit, a first receive antenna coupled to the processing unit, and a second receive antenna coupled to the processing unit, wherein the processing unit is programmed to enable:
- a first radar reading based on the first transmit antenna transmitting a first transmit sequence toward an object such that (a) the first receive antenna receives a first echo of the first transmit sequence off the object and (b) the second receive antenna receives a second echo of the first transmit sequence off the object,
- a second radar reading based on the second transmit antenna transmitting a second transmit sequence toward the object such that (a) the first receive antenna receives a third echo of the second transmit sequence off the object and (b) the second receive antenna receives a fourth echo of the second transmit sequence off the object, and
- an action based on the first radar reading and the second radar reading.
A system, comprising:
- a land vehicle hosting a time-of-flight (TOF) radar including a processing unit, a first transmit antenna coupled to the processing unit, a second transmit antenna coupled to the processing unit, a first receive antenna coupled to the processing unit, and a second receive antenna coupled to the processing unit, wherein the processing unit is programmed to enable:
- a first radar reading based on the first transmit antenna transmitting a first transmit sequence toward an object such that (a) the first receive antenna receives a first echo of the first transmit sequence off the object and (b) the second receive antenna receives a second echo of the first transmit sequence off the object,
- a second radar reading based on the second transmit antenna transmitting a second transmit sequence toward the object such that (a) the first receive antenna receives a third echo of the second transmit sequence off the object and (b) the second receive antenna receives a fourth echo of the second transmit sequence off the object, and
- an action based on the first radar reading and the second radar reading.
A method, comprising:
- enabling an operation of a time-of-flight (TOF) digital radar-on-chip including a processing unit, a first transmit antenna coupled to the processing unit, a second transmit antenna coupled to the processing unit, a first receive antenna coupled to the processing unit, and a second receive antenna coupled to the processing unit, wherein the processing unit is programmed to enable:
- a first radar reading based on the first transmit antenna transmitting a first transmit sequence toward an object such that (a) the first receive antenna receives a first echo of the first transmit sequence off the object and (b) the second receive antenna receives a second echo of the first transmit sequence off the object,
- a second radar reading based on the second transmit antenna transmitting a second transmit sequence toward the object such that (a) the first receive antenna receives a third echo of the second transmit sequence off the object and (b) the second receive antenna receives a fourth echo of the second transmit sequence off the object, and
- an action based on the first radar reading and the second radar reading.
