Patent number: 11428782Abstract: Systems and methods to perform object surface estimation using a radar system involve receiving reflected signals resulting from reflection of transmit signals by an object. The method includes processing the reflected signals to obtain an image. The image indicates an intensity associated with at least one set of angle values and a set of range values. The method also includes processing the image to provide the object surface estimation. The object surface estimation indicates a subset of the at least one set of angle values and associated ranges within the set of range values.Type: GrantFiled: May 2, 2019Date of Patent: August 30, 2022Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Oded Bialer, Tom Tirer, David Shapiro, Amnon Jonas

Patent number: 11046328Abstract: Systems, vehicles, and techniques are provided for the estimation of a linear velocity vector of an object. In some embodiments, a technique can include receiving first data indicative of first locations relative to an object at a first instant during movement of the object, and receiving second data indicative of second locations relative to the object at a second instant during the movement of the object. The technique also can include transforming the first data into third data corresponding to the second instant using at least one velocity vector hypothesis for a velocity of the object. The technique can further include solving an optimization problem with respect to a geometric volume of a convex hull of a union of the second data and the third data, and generating an estimate of a velocity of the object using a solution of the optimization problem.Type: GrantFiled: September 25, 2018Date of Patent: June 29, 2021Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Tom Tirer, Oded Bialer

Patent number: 10976411Abstract: Systems, vehicles, and techniques are provided to classify reflection detection points in a sensing system. A reflection detection point can be classified as an apparent reflection or a physical reflection. In some embodiments, a beamforming map can be generated using a response function of an antenna array and data representative of electromagnetic signals received at the antenna array. Multiple reflection detection points can be detected using at least the beamforming map. A second beamforming distribution map also can be generated, using at least the data and a second response function of the array of antennas. The second response function includes minima at respective reflection points. A ratio between (i) a first amplitude of a reflection detection point in the second beamforming map and (ii) a second amplitude of the reflection point in the first beamforming map permits classifying the reflection detection point as an apparent reflection or a physical reflection.Type: GrantFiled: September 25, 2018Date of Patent: April 13, 2021Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Oded Bialer, Tom Tirer

Patent number: 10908273Abstract: A vehicle, system and method of estimating a velocity of an object with respect to the vehicle is disclosed. The system includes a plurality of radars associated with the vehicle and a processor. The plurality of radars provide a coarse estimate of the velocity. The processor obtains a plurality of velocity hypotheses based on the coarse estimate of the velocity of the object, determines a likelihood for each of the plurality of velocity hypotheses, and chooses a velocity hypothesis having as the estimate of velocity based on the determined likelihood.Type: GrantFiled: August 10, 2018Date of Patent: February 2, 2021Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Oded Bialer, Amnon Jonas, Tom Tirer

Patent number: 10551493Abstract: A vehicle, a radar system for the vehicle, and method of driving the vehicle. A radar array having plurality of radar nodes is arranged along the vehicle. Each radar node includes a first transmitter at one end of the node, a second transmitter at a second end of the node and a plurality of receivers aligned between the first transmitter and the second transmitter. At least one of an aperture length of the nodes and a spacing between the nodes is a variable parameter. A processor activates a transmitter of the radar array to generate a test pulse, receive, at a receiver of the radar array, a reflection of the test pulse from an object, and determines an angular location of the object from the reflection of the test pulse. A trajectory of the vehicle can be changed using the determined angular location of the object.Type: GrantFiled: August 18, 2017Date of Patent: February 4, 2020Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Oded Bialer, Amnon Jonas, Tom Tirer
