Abstract: A system includes a processor and a non-transitory computer-readable medium storing machine instructions that cause the processor to perform a first fast Fourier transform (FFT) on received radar data to obtain a range-antenna data array and to perform a second FFT on the range-antenna data array to obtain a range-Doppler-antenna data cube. The processor performs peak detection on the range-Doppler-antenna data cube based on object information to obtain a subset that includes confirmed peaks and candidate peaks. The processor performs angle of arrival calculations for the subset of the range-Doppler-antenna data cube, and filters candidate peaks in the subset to obtain a point cloud representative of an environment. In some implementations, the confirmed peaks are detected based on a default threshold value, the candidate peaks are detected based on at least one adapted threshold value, and the at least one adapted threshold value is determined based on the object information.

Abstract: A radar data processing system is disclosed. The system includes a microcontroller and a data receiver-transmitter integrated circuit coupled to the microcontroller. The data receiver-transmitter integrated circuit includes a sensor and a dedicated error indicator pin. The data receiver-transmitter integrated circuit includes an inner safety monitor and the microcontroller includes an outer safety monitor. The inner safety monitor configured to receive and collate sensor data from the plurality of sensors and send, through the dedicated error indicator pin, a function warning signal to the outer safety monitor when the sensor data from the sensor is indicative of a functional irregularity.

Abstract: The disclosure relates to a processing module and associated method for calibrating an object-detection system for a vehicle comprising a plurality of object-detection sensors. The method comprises receiving, from each of a plurality of the object-detection sensors, a value associated with the detection of a marker; and determining a position of each of the object-detection sensors with respect to the vehicle based on the received values associated with the detection of the marker.

Abstract: A radar transceiver is disclosed. The radar transceiver includes a computing unit, a sweep control unit, a set of transmitters for transmitting radar chirps to targets, a set of receivers for receiving reflected chirps from the targets, and a timing engine processor coupled to the set of transmitters and to the set of receivers and configured to transmit a first set of control signals. The timing engine processor receives a second set of control signals generated by the computing unit. The sweep control unit receives a first control signal and a second control signal from the timing engine processor. The first control signal indicating a start time of a chirp and the second control signal indicating a reset time for resetting the chirp. A controlled phased lock loop (PLL) generates a local oscillator signal which is inputted to transmitters and receivers.
