摘要： A system for interpolating wireless spectrum. The system may include an antenna system operable for transmitting wireless signals and responsively receiving reflected signals. The system may additionally include an interpolation controller configured for collecting a plurality of reflection radar spectrum samples from the reflected signals, identifying an interpolation point between two or more interpolation samples of the samples, calculating an interpolation weight for the each of the interpolation samples, and determining an interpolated spectrum at the interpolation point as a summation of a product of the interpolation weights and the interpolation samples.

摘要： A motion monitor includes a lidar device, a controller, and a circuit. The lidar device is configured to perform scans of an environment proximate the ego vehicle to generate lidar point clouds related to one or more objects in the environment. The controller is configured to transform the lidar point clouds with location transform matrices to generate location point sets, aggregate the location point sets in a duration of interest to generate aggregated point sets, register the location point sets to the aggregated point sets to generate correction transform matrices, update the location transform matrices with the correction transform matrices to generate updated location transform matrices, and generate motion sets based on the updated location transform matrices. The circuit is configured to receive the motion sets.

摘要： A system and method to detect an object with a radar system involve transmitting two or more sets of linear frequency modulated signals with a gap duration Dg, during which there is no transmission, between each of the two or more sets of the linear frequency modulated signals. Each of the two or more sets of the linear frequency modulated signals defines a sub-frame, and two or more sub-frames defines a frame. The method includes receiving reflections resulting from the linear frequency modulated signals encountering one or more objects in a field of view of the radar system, and processing the reflections to identify the one or more objects. The processing includes performing an on-off Radon transform to correct a phase bias caused by the gap duration during which there is no transmission.

摘要： 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.

摘要： 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.

摘要： A radar system includes a transmit channel, and a transmit antenna to transmit a signal generated by the transmit channel. The radar system also includes a movement device to cause controlled movement of the transmit antenna. A controller controls the movement device. The controlled movement is used to improve an estimate of azimuth angle to an object detected by the radar system.

摘要： A method for using Synthetic Aperture Radar (SAR) to perform a maneuver in a land vehicle is provided. The method includes: receiving digitized radar return data from a radar transmission from a SAR onboard the vehicle; accumulating a plurality of frames of the digitized radar return data; applying a RADON transform to the accumulated plurality of frames of the digitized radar return data and odometry data from the vehicle to generate transformed frames of data for each three-dimensional point, wherein the RADON transform is configured to perform coherent integration for each three-dimensional point, project a radar trajectory onto each three-dimensional point, and project Doppler information onto each three-dimensional point; generating a two-dimensional map of an area covered by the radar transmission from the SAR based on the transformed frames of data for each three-dimensional point; and performing a maneuver with the land vehicle by applying the generated two-dimensional map.

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.
