Abstract
An apparatus and a method for simultaneously measuring velocity and an instantaneous spatial position of a spherical object. A first group of sensors and a second ground of sensors are arranged at known positions at intervals each less than the radius of the spherical object. The times when the spherical object begins to intercept the sensors of the groups of sensors and the time lengths of the respective interceptions are measured by using an instrumentation device. The velocity and instantaneous spatial position of the spherical object are calculated by using an arithmetic unit on the basis of the measured times and time lengths.
