Publication number: 20220236409Abstract: A method includes obtaining an initial point cloud for each of two or more radar systems that share a common field of view. Each initial point cloud results from processing reflected energy at each of the two or more radar systems. Each point of the initial point cloud indicates one or more hypotheses for a range, a Doppler, and a direction of arrival (DOA) to an object that resulted in the reflected energy. A point cloud, obtained from the initial point cloud, has a same number of hypotheses for the range, the Doppler, and the DOA. Resolving ambiguity in the common field of view is based on the point clouds to obtain resolved and unresolved points in the common field of view. A radar image obtained from each of the two or more radar systems is used to control an aspect of operation of a vehicle.Type: ApplicationFiled: January 25, 2021Publication date: July 28, 2022Inventors: Gaston Solodky, Ishai Eljarat, Igal Bilik, Gonen Barkan

Patent number: 11385328Abstract: A vehicle, radar system for the vehicle and method for detecting an object. The radar system includes a transmitter for transmitting a source signal and a receiver for receiving a reflection of the source signal from an object. A processor obtains a radar parameter of the object from the received reflection, adjusts an operating parameter of the radar based on the radar parameter to provide an altered source signal, and detects the object based on a reflection of the altered source signal.Type: GrantFiled: August 14, 2018Date of Patent: July 12, 2022Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Gaston Solodky, Oren Longman, Shahar Villeval, Igai Bilik

Patent number: 11249165Abstract: A hyperbolic waveform multiple-input multiple-output radar includes a generator circuit, multiple transmit circuits, a multiple-input multiple-output antenna, and multiple receive circuits. The generator circuit may be operable to generate a linear frequency modulated signal and a hyperbolic frequency modulated signal. The transmit circuits may be operable to generate multiple transmit signals by analog mixing the linear frequency modulated signal and the hyperbolic frequency modulated signal in response to a plurality of coding family parameters, wherein the transmit signals define an orthogonal family of waveforms. The multiple-input multiple-output antenna may be operable to transmit the transmit signals toward an object and receive multiple receive signals from the object. The receive circuits may be operable to determine multiple data signals in response to the receive signals, wherein the data signals are suitable to determine a distance between the multiple-input multiple-output antenna and the object.Type: GrantFiled: August 1, 2019Date of Patent: February 15, 2022Assignee: GM Global Technology Operations LLCInventors: Gaston Solodky, Oren Longman, Shahar Villeval, Igal Bilik

Patent number: 11209537Abstract: A radar circuit for use with a host system such as a vehicle includes a radio frequency (RF) signal generator configured to generate a predetermined RF waveform, an RF antenna connected to the RF signal generator, and an ECU which executes a method. As part of such a method, a signal generator transmits the RF waveform toward different radar target types, and receives return signatures reflected therefrom. The ECU receives the return signatures from the antenna, processes the return signatures via parallel constant false-alarm rate (CFAR) subdetectors each with defined cells under test to detect the target types as a set of detection events, merges the detection events into a merged set, and executes a control action aboard the host system responsive to the merged set. Each subdetector detects a corresponding one or more of the radar target types via corresponding detection parameters.Type: GrantFiled: June 18, 2019Date of Patent: December 28, 2021Assignee: GM Global Technology Operations LLCInventors: Oren Longman, Gaston Solodky, Shahar Villeval, Igai Bilik

Patent number: 10996326Abstract: A system and method to generate a family of orthogonal signals for a code division multiple access (CDMA) radar system involve selecting a first signal of the family of orthogonal signals for transmission by one of a plurality of transmitters of the radar system. The method includes using an algorithm to determine a second signal of the family of orthogonal signals. The algorithm uses cross-correlation values between candidate signals for consideration as the second signal of the family of orthogonal signals and the first signal. The method also includes transmitting the first signal of the family of orthogonal signals and the second signal of the family of orthogonal signals simultaneously from two different transmitters, and obtaining and processing reflections resulting from transmission of the first signal of the family of orthogonal signals and the second signal of the family of orthogonal signals.Type: GrantFiled: November 13, 2018Date of Patent: May 4, 2021Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Gaston Solodky, Oren Longman, Shahar Villeval, Igal Bilik

Patent number: 10795013Abstract: A system and method to perform multi-target detection in a code division multiple access (CDMA) radar system involve transmitting, from each transmitter among T transmitters, a transmitted signal with a different code, and receiving, at each receiver among one or more receivers, a received signal that includes reflections resulting from each of the transmitted signals with the different codes. The method includes processing the received signal at each of the one or more receivers by implementing T processing chains. Each of the T processing chains is iterative. The method also includes detecting an object at each completed iteration at each of the T processing chains, and subtracting a subtraction signal representing a contribution of the object to the received signal prior to subsequent iterations.Type: GrantFiled: November 7, 2018Date of Patent: October 6, 2020Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Gaston Solodky, Shahar Villeval, Oren Longman, Igal Bilik
