    Abstract: A radar system suitable for an automated vehicle includes a plurality of antennas configured to detect a reflected radar signal reflected by an object in a field-of-view of the system. Each antenna of the plurality of antennas is configured to output detected signals indicative of the reflected radar signal detected by each of the plurality of antennas. The system also includes a controller configured to receive the detected signals from the plurality of antennas, determine if the object is present in the field-of-view based on the detected signals, and determine a phase-difference between symmetrical-frequency-bins for each antenna. The symmetrical-frequency-bins are symmetrically offset from a maximum-amplitude non-coherent-integration detection-frequency-bin (max-NCI-bin). The controller is further configured to determine a classification of the object based on a time-domain-analysis of the phase differences across the plurality of antennas.

    Abstract: A radar system includes a controller equipped with memory for storing data. The controller is configured to receive a time-domain signal representative of a reflected signal detected by an antenna, and transform the time-domain signal into a plurality of range datasets. Each range dataset corresponds to one of the plurality of chirps, each range dataset is represented by a series of values assigned to a plurality of range bins, and each of the values includes a sign bit. The controller is also configured to compress the plurality of range datasets by storing in the memory a portion of each of the values assigned to at least one of the plurality of range bins, wherein the portion is defined to exclude a first number of redundant sign bits of each value. The controller may further compress the portion by retaining a second number of bits of the data by excluding some of the least significant bits of each value.

    Abstract: There is provided a radar apparatus. A predicting unit predicts a current peak signal based on a pervious determined peak signal. An extracting unit extracts a current peak signal corresponding to the predicted peak signal, from among peak signals existing within a predetermined range of the frequency. A filtering unit performs a filtering process on the predicted peak signal and the current peak signal, and output a result of the filtering process as a current determined peak signal. If the target derived based on the current peak signal is a preceding vehicle existing in front of an own vehicle equipped with the radar apparatus, the filtering unit changes whether to perform the filtering process according to a state of the preceding vehicle.
