Abstract: A method includes assessing errors for golf shots using observations by sensor(s), the assessing being in accordance with variations in a location for the sensor(s), and providing a map indicating at least one preferred location for the sensor(s) for use in setting up an object tracking system. Further, a method includes assessing how an estimated error affects identification of an originating location for a golf shot, including projecting a first value of the error back to the originating location and multiplying a second value of the error by a distance to the originating location, and identifying the originating location for the golf shot based on a first effect of the error and a second effect of the error. Finally, a system includes a building including tee areas, targets, and a sensor system including sensor(s), in which a dedicated sensor system is not included for any one of the tee areas.

Abstract: A method for estimating a spin of a projectile, the method comprising obtaining a first data series representing a radial velocity of a projectile over time in accordance with a radar signal reflected from the projectile, subtracting a center velocity of the first data series from the first data series to form a second data series representing a variation of the radial velocity of the projectile around the center velocity over time, dividing the second data series into respective time intervals, estimating, for each of the time intervals of the second data series, a frequency of the variation of the radial velocity of the projectile around the center velocity, and determining a spin of the projectile based on the estimated frequencies of the variation of the radial velocity of the projectile.

Abstract: A post for mounting a camera comprises a base, a tube mast, and a camera mount arranged to hold one or more cameras. A proximal end of the tube mast is connected to the base and a distal end of the tube mast is connected to the camera mount. The invention is characterised in that the base is arranged to comprise computing equipment, from which computing equipment wiring runs through the tube mast to the camera mount, and in that the base and computing equipment are encased by a cabinet configured to protect the computing equipment from exposure to weather. The invention also relates to a method for installing a post.

Abstract: Method for providing reduced interference for at least two co-located FMCW (Frequency Modulated Continuous Wave) Doppler radars, each of said radars being used in a system to detect respective distances to and velocities of objects moving through space, can include a propagation determination step, in which expected electromagnetic wave propagation times are determined between pairs of radars; a sweep time offset synchronizing step, in which different respective sweep time offsets are selected, with respect to each radar in a first group of radars; and a sweep frequency offset synchronizing step, in which a second sweep frequency offset is selected with respect to a second group of radars, the second sweep frequency offset being relative to a sweep frequency pattern used for radars belonging to said first group. The invention also relates to a system and to a computer software product.
