Abstract:
A method of providing at least two parameter values pertaining to a relative kinematic behavior of an object and a target object, for which a conclusion is determinable based on the at least two parameter values as to whether the object and the target object will probably collide, the method comprising:providing on the object a sensor system to transmit and receive a plurality of signals to determine at least two measured values for at least one of a distance and a relative radial velocity of the target object; determining the at least two measured values; analyzing the at least two measured values based on the plurality of signals received by a receiver; and providing the at least two parameter values based on analyzing the at least two measured values; wherein a vector {right arrow over (p)} contains the at least two parameter values and is of the form: {right arrow over (p)}=[a,v0,&agr;0, â€ƒwhere a is a relative acceleration of the target object, v0 is a relative initial velocity of the target object in a first measurement, and &agr;0 is an angle between vectors of a relative velocity of the target object and the relative radial velocity of the target object, corresponding to an angle between vectors of the relative acceleration of the target object and a relative radial acceleration of the target object in the first measurement.
