摘要： Systems and methods involve detecting objects using a radar system of a vehicle. Tracks of the objects are initiated in a track database. The tracks store data, respectively, for the objects and are updated based on additional detections of the objects. The tracks of the objects are initially unclassified tracks. Two tracks corresponding to two of the objects are selected as a candidate pair. Criteria are applied to the candidate pair to determine whether one track is of a ghost object and another track is of a true object corresponding with the ghost object. The ghost object represents detection of the true object in an incorrect location. The candidate pair is classified as tracks of a true object and ghost object pair based on determining that the one track is of the ghost object and the other track is of the true object corresponding with the ghost object.

摘要： A method and system include transmitting transmit signals from a radar system. The transmit signals are linear frequency modulated continuous wave signals. The method includes receiving reflected signals at the radar system based on reflection of at least at subset of the transmit signals by one or more objects. A range from the radar system associated with each of the reflected signals corresponds with a frequency of the reflected signal. The reflected signals are processed to identify and locate the one or more objects. Processing includes applying an adaptive range-selective gain control (ARSGC) to control a gain corresponding with each of the reflected signals based on the range associated with the reflected signal.

摘要： A radar system for use in a vehicle may include a radar transmitter structured to transmit a radar signal having a waveform; and a controller operably connected to the radar transmitter and configured to control the waveform. The waveform may be characterized by a waveform parameter. The controller may be configured to set a value of the waveform parameter based on a present operational state of the vehicle, thereby generating an updated waveform. The radar transmitter may be structured to transmit an updated radar signal having the updated waveform.

摘要： A system and method for obtaining an overall image that is constructed from multiple sub-images. The method includes: capturing a first sub-image having a first sub-image field of view using an image sensor of an electronically-steerable optical sensor; after capturing the first sub-image, steering light received at the electronically-steerable optical sensor using an electronically-controllable light-steering mechanism of the electronically-steerable optical sensor so as to obtain a second sub-image field of view; capturing a second sub-image having the second sub-image field of view using the image sensor of the electronically-steerable optical sensor; and combining the first sub-image and the second sub-image so as to obtain the overall image.

摘要： A scanning and perception system for a vehicle camera having an instantaneous field of view (iFOV) and configured to capture an image of an object at a saturation level in the camera's iFOV. The system also includes a light source configured to illuminate the camera's iFOV. The system additionally includes a radar configured to determine the object's velocity and the object's distance from the vehicle, and a mechanism configured to steer the radar and/or the camera. The system also includes an electronic controller programmed to regulate the mechanism and adjust illumination intensity of the light source in response to the saturation level in the image or the determined distance to the object. The controller is also programmed to merge data indicative of the captured image and data indicative of the determined position of the object and classify the object and identify the object's position in response to the merged data.

摘要： System and method of controlling operation of a device in real-time. The system includes an optical sensor having a steerable optical field of view for obtaining image data and a radar unit having a steerable radar field of view for obtaining radar data. A controller may be configured to steer a first one of the optical sensor and the radar unit to a first region of interest and a second one of the optical sensor and the radar unit to the second region of interest. The controller may be configured to steer both the optical sensor and the radar unit to the first region of interest. The radar data and the image data are fused to obtain a target location and a target velocity. The controller is configured to control operation of the device based in part on at least one of the target location and the target velocity.

摘要： A system and method to perform target tracking with a radar system that uses a Kalman filter include predicting a predicted target position of a target detected by the radar system in a frame. The frame is a period of time to transmit from every transmit element of the radar system in turn and receive the reflections from a range of the target. The method also includes determining an actual target position of the target detected by the radar system based on reflections received by the radar system for the frame, and computing a process noise covariance matrix Q for a next frame, immediately following the frame, based on the predicted target position and the actual target position. Predicting a position of the target in the next frame is based on the process noise covariance matrix Q.

摘要： A method and apparatus for determining a distance between a first radar system disposed on a vehicle and a second radar system disposed on the vehicle. A target reflector is moved along a track to a location along a perpendicular bisector of a baseline connecting the first radar system and the second radar system. A direct range measurement is obtained for at least one of the first radar system and the second radar system, and a bistatic range measurement is obtained between the first radar system and the second radar system. A processor determines the distance between the first radar system and the second radar system using the direct range measurement, the bistatic range measurement and a radial length of the target reflector.
