A vehicle radar system () which, for each one of a plurality of radar cycles, is arranged to, provide a measured azimuth angle (&#x3b8;) and radial velocity (v) for a first plurality of detections (). For each one of the plurality of radar cycles, the radar system () is arranged to select one of these detections for each one of two velocity components (v, v) in a set of components (v, v, a, a; a) to be determined; select one detection from a second plurality of detections () for each one of at least one corresponding acceleration component (a, a; a); calculate the components (v, v, a, a; a) for the selected detections; determine a calculated radial velocity (v) for each one of at least a part of the other detections in the first plurality of detections () using the calculated components (v, v, a, a; a); determine an error between each calculated and measured radial velocity (v, v); and determine the number of inliers. The set of components (v, v, a, a; a) that results in the largest number of inliers is then chosen.

Determining object motion and acceleration vector in a vehicle radar system

A vehicle radar system () and related method including at least one transceiver arrangement () arranged to generate and transmit radar signals (), and to receive reflected radar signals (). The radar signals form a plurality of sensing sectors or sensing bins (-), that together form a transceiver coverage (), For each sensing bin (-) the radar system () is arranged to obtain a target angle (&#x3c6;) and a target range (r) to possible target objects (-). The radar system () is further arranged to determine an unoccupied domain border () and a corresponding unoccupied domain () for the radar transceiver coverage ().

Vehicle radar system arranged for determining an unoccupied domain

A vehicle environment detection system () that includes at least one radar sensor arrangement () and at least one processing unit (), where the radar sensor arrangement () is arranged to detect at least two radar detections () during at least two radar cycles. For each radar cycle, the processing unit () generates a detection list ({D}) including range (r), azimuth angle (&#x3c6;) and Doppler velocity (v) for each of the radar detections (). The processing unit () is further arranged to aggregate and store detection lists ({D}) from the radar cycles in a detection memory (), and then to group the radar detections () in the detection lists ({D}) into consistently moving motion subsets () in a segmentation procedure. Each motion subset () corresponds to a certain target object ().
