Methods and means to uniquely identify an object

The invention relates to a unique identification of an object a) placing at least one unique identification agent on or in a space formed as a missile object; Transmitting an electromagnetic wave having transmission signal from a transmitting station to said identification means of that are available in the space missile space; Receiving a returned from the identification means of the space missile in response to the transmit electromagnetic wave signal having the identification signal in a receiving station; unambiguous identification of the space missile from the identification signal; b) placing at least one unique identification means, which is adapted for directional radiation back an identification signal in response to a transmission signal having a defined reflection direction of an object; Transmitting an electromagnetic wave having transmission signal from a transmitting station to the identification means of the object; Receiving a directed from the identification means of the object in response to the transmission signal reflected back identification signal in a receiving station; uniquely identifying the object based on the identification signal.
