  • Patent number: 10677907
    Abstract: A method to determine the heading or orientation of a target vehicle by a host vehicle, said host vehicle equipped with a lidar or radar system, said system including a sensor unit adapted to receive signals emitted from said host vehicle and reflected by said target vehicle, comprising: a) determining at least one reference angle being an initial estimate of target heading or orientation (?); b) emitting a signal from said system and determining a plurality of point radar or lidar detections belonging to said a target vehicle, said point detections having co-ordinates in the horizontal plane; c) formulating an initial rectangular boundary box from said point detections, where the bounding box is formulated such that such that two edges of the boundary box are drawn parallel to the reference angle and two sides are perpendicular to the reference angle and such that all the detections are either on the bounding box sides or lay within the bounding box and each edge has at least one detection point on it; d) fo

  • Patent number: 10634766
    Abstract: A method of determining the de-aliased range rate of a target in a horizontal plane by a host vehicle equipped with a radar system, said radar system including a radar sensor unit adapted to receive signals emitted from said host vehicle and reflected by said target, comprising: emitting a radar signal at a single time-point instance and determining from a plurality (m) of point radar detections measurements therefrom captured from said radar sensor unit, the values for each point detection of, azimuth and range rate; [?i, {dot over (r)}i]; for each point detection determining a range rate compensated value ({dot over (r)}i,cmp); c) determining a plurality (j) of velocity profile hypotheses; for each (j-th) hypothesis determining modified compensated hypothesis range rates ({dot over (r)}i,j,cmp) in respect of each point detection on the target, based on the values of range rate compensated ({dot over (r)}i,cmp); for each j-th hypothesis, determining values of the longitudinal and lateral components of the ra

  • Publication number: 20200057090
    Abstract: A method of determining an uncertainty estimate of an estimated velocity of an object includes, determining the uncertainty with respect to a first estimated coefficient and a second estimated coefficient of the velocity profile equation of the object. The first estimated coefficient being assigned to a first spatial dimension of the estimated velocity and the second estimated coefficient being assigned to a second spatial dimension of the estimated velocity. The velocity profile equation represents the estimated velocity in dependence of the first estimated coefficient and the second estimated coefficient. The method also includes determining the uncertainty with respect to an angular velocity of the object, a first coordinate of the object in the second spatial dimension, and a second coordinate of the object in the first spatial dimension.

  • Publication number: 20190361106
    Abstract: The present invention relates to a method of estimating a velocity magnitude of a moving target in a horizontal plane using radar signals received by a radar detection system, the radar detection system being configured to resolve multiple dominant points of reflection, i.e. to receive a plurality of radar signals from the moving target in a single measurement instance of a single, wherein each of the resolved points of reflection is described by data relating to a range, an azimuth angle and a raw range rate of the points of reflection in said single radar measurement instance. The invention further relates to a radar detection system.
