The vehicle odometry and motion direction system and method is described. The vehicle odometry and motion direction system and method determines if the first ground speed data is acceptable. Ground speed data is calculated for all targets within a radar's field of view and targets ground speed data is processed to determine second ground speed data. The vehicle odometry and motion direction system and method determines trusted ground speed data using first ground speed data and second ground speed data and adjusts the trusted ground speed data due to errors in radar Doppler speed data.

A vehicle radar sensor utilizes Frequency Modulated Continuous Wave (FMCW) radar signals that incorporate non-uniform FMCW chirps having chirp profiles that differ from one another to sense one or more parameters of one or more objects in a field of view of the radar sensor. The chirp profiles may differ from one another in various manners, e.g., based on starting frequency, repetition interval, duration and/or slope, and among other advantages, may be used to enhance sensing of various parameters such as range, Doppler/velocity and/or angle.

A method for manufacturing a heatable plastic component for a motor vehicle, which includes: providing a planar heating film, which has a first surface and a second surface that faces away from and is opposite the first surface, including at least one heating wire and connecting elements; introducing the planar heating film into an injection mold; mounting a connector housing onto the connecting elements; and back-molding the first surface with a plastic for manufacturing a first partial element of the heatable plastic component in the injection mold. In order to provide an improved method for manufacturing a heatable plastic component, it is proposed that a back-molding of the second surface with a plastic for manufacturing a second partial element of the heatable plastic component in the injection mold takes place such that a composite is formed from the first partial element, the planar heating film and the second partial element.

This application discloses a signal receiving method and device, a medium, and a radar system. The radar system includes: a window, a radar transmitter, a radar receiver, a processor, and a signal receiving circuit. The radar transmitter is configured to: transmit a radar detection signal to a front obstacle through the window. The radar receiver is connected to the signal receiving circuit, and receive a reflected signal generated by the obstacle, and transmit the reflected signal to the signal receiving circuit. The signal receiving circuit is connected to the processor, and when the radar transmitter transmits the radar detection signal, receive, after preset duration, the reflected signal where the preset duration is a sum of first duration required for the radar detection signal to arrive at the window and second duration required for the reflected signal to arrive at the radar receiver from the window.

This document describes techniques, apparatuses, and systems for radar interference mitigation using signal pattern matching. Radar signals (e.g., chirps) received by a radar system may include interference from other nearby radar systems. The interference can result in reduced sensitivity of the radar system. The techniques, apparatuses, and systems described herein mitigate the interference by selecting an uncorrupted segment of the radar signal that neighbors a corrupted segment, analyzing the radar signal to identify a match segment that has similar signal characteristics to the neighbor segment, and replacing the corrupted segment with a segment that is adjacent to the match segment. In this manner, a noise floor of the radar system may be lowered, leading to increased sensitivity.
