Abstract: A radar system comprises a plurality of transmit antennas that transmit a radar signal toward a target, wherein respective transmit antennas are assigned a transmitter-specific phase offset via which the radar signal is modulated, and wherein respective phase offsets correspond to an offset in velocity of a target. The system further comprises a plurality of receive antennas that receive comprising transmitted signals reflected by the target, and one or more processors configured to determine whether a peak signal is present for respective transmitted signals reflected by the target, the peak signals corresponding to perceived velocities at which the target is moving.

Abstract: Various technologies described herein pertain to a radar sensor system that performs ego motion estimation. A radar sensor system can be utilized to generate an instantaneous three-dimensional ego motion estimate of a vehicle. The radar sensor system employs an algorithm that enables generating ego motion estimates for velocities of the vehicle that can be greater than, less then, or equal to the unambiguous maximum velocity of the radar sensor system. Moreover, a single radar sensor system of a vehicle can implement the approaches set forth herein and the techniques can be applicable regardless of modulation of the radar sensor system.

Abstract: A radar system comprises a plurality of receive antennas that receive a radar signal. One or more processors are configured to perform acts selecting one or more training cells for noise power estimation based upon a radar signal received at one or more receive antennas. The acts further comprise calculating a mean noise power value for the one or more training cells and calculating a noise power variance for the one or more training cells. The acts also comprise estimating a probability of false alarm (PFA) threshold to be applied for a non-training cell and estimating a PFA threshold offset based on the noise power variance. The acts further comprise adjusting a current PFA threshold offset based on the estimated PFA threshold offset.

Abstract: A radar sensor is disclosed herein, where the radar sensor detects blockage based upon detected radar signals. The radar sensor includes an antenna that detects electromagnetic radiation in a field of view and processing circuitry that is operably coupled to the antenna. Raw sensor data is generated based upon the detected electromagnetic radiation. A detection list is computed based upon the raw sensor data, and a blockage state for the radar sensor is computed based upon the detection list and the raw sensor data.

Abstract: Various technologies described herein pertain to systems and methods for increasing radar resolution by, for example, combining radar information. In one embodiment, beamforming is performed using radar units that are individually coherent but collectively do not need to be coherent. Each radar transmits and receives its own signal to process and generate target information including beamforming information and/or virtual receiver channel information. The target information from each radar is then merged or summed into a combined beamforming based on all the target information received from all the radar units. When the radar units used in this manner are separated by a distance, the resulting beamforming information is representative of an aperture/resolution based on the total space or distance between the radar units. Thus, having an improved resolution, benefits such as improved target resolution (e.g., size, position, and detection) can be achieved.

Abstract: A radar sensor system comprises a first radar sensor and at least a second radar sensor and one or more processors configured to assign different pulse rate intervals (PRI) to the first radar sensor and the second radar sensor. The processor(s) s are further configured to: receive ambiguous velocity estimates from the first and second radar sensors, respectively; determine maximum detectable velocity (Vmax) values for the first and second radar sensors based on their respective PRIs; generate a first velocity vector for the first radar sensor based on the first Vmax and the first ambiguous velocity estimate; generate a second velocity vector for the second radar sensor based on the second Vmax and the second ambiguous velocity estimate; compare velocity values in the first and second velocity vectors; and identify and output a velocity value common to the first and second velocity vectors as a correct unambiguous velocity of the object.

Abstract: A radar system is configured to transmit via transmit antenna a digitally modulated carrier signal in successive transmission frames using different frequency subbands for each transmission frame, such that contiguous transmission frames do not use the same frequency subband. A receive antenna is configured to receive a radar return signal reflected by a target on a frequency subband used by the transmit antenna in the immediately preceding transmission frame so that the transmit antenna and the receive antenna use different subbands in a given transmission frame.

Abstract: A radar sensor system comprises a transmit antenna configured to transmit a radar signal into an environment of the radar sensor system, and a receive antenna configured to receive a return signal from the environment of the radar sensor system responsive to the radar signal. The radar sensor system further comprises radar processing circuitry that is configured to perform acts comprising transmitting a radar signal having a predefined pulse repetition interval (PRI). The acts further comprise monitoring ego velocity of the radar sensor and detecting that the ego velocity has exceeded a first predetermined ego velocity threshold. The acts also comprise decreasing the predefined pulse repetition interval (PRI) based on the first predetermined ego velocity threshold.

Abstract: Various technologies described herein pertain to systems and methods for broadband radar(s) having broadband antenna systems including, for example, antennas and components. In one aspect, a system is disclosed having a dielectric structure that includes two or more dielectric heights and/or effective dielectric constant values. A first dielectric height and/or effective dielectric constant value is used for a transmission feed portion of the system and a second dielectric height and/or effective dielectric constant value is used for an antenna portion of the system. In one embodiment, the second dielectric height is greater than the first dielectric height and is selected to provide the antenna portion with a selected frequency range.
