A method for identifying an object, a transceiver station, an identification arrangement and a system for identifying the object are provided and include a transceiver station with a source for generating a pulse train from pulses of electromagnetic radiation and an identification arrangement arranged on the object. The source sends pulses from the pulse train in the direction of the object. A receive signal is transmitted back from the identification arrangement to the transceiver station in response to each transmission signal. Two polarization states of the received signal offset in time by the transit time of the received signal from the object to the transceiver station are detected with two detectors and an actual identification pattern of the object is formed by aggregating the intensities of the polarization states of several successive received signals. A time shift of the receive signals relative to a trigger signal synchronized with the pulse train of the source is also detected.
A method for identifying an object, with a system which has at least one transceiver station with a source for generation of a pulse train of pulses of electromagnetic radiation and at least one identification means arranged on the object, wherein the source sends the pulses of the pulse train as a transmit signal in the direction of the object and from the at least one identification means of the object, an electromagnetic receive signal is radiated back to the transceiver station in response to each transmit signal, wherein at least two polarization states of the receive signal are detected with a time offset equal to the transit time of the receive signal from the object to the transceiver station with at least two detectors and an actual identification pattern of the object is formed by aggregation of the detected intensities of the polarization states of several successive receive signals, wherein, in addition to the polarization states, a time shift of the individual receive signals relative to a trigger signal synchronized with the pulse train of the source is also detected and the identification pattern is expanded by the information about the time shift of the receive signal.
A transceiver station for identifying an object, in particular a satellite in space, with at least one source of electromagnetic radiation for emitting a pulsed transmit signal as a pulse train to the object and with a telescope for receiving receive signals reflected back from the object, wherein the receiving station comprises a polarization state analyzer for determination of the receive signal polarization states of the receive signals reflected back from the object, wherein the polarization state analyzer comprises a time measuring unit in order to detect the polarization and the time shift of the pulses of a multiple pulse at a reference time synchronized with the pulse train of the source.
An identification arrangement for identifying an object, the identification arrangement comprising at least one retroreflector assembly, which is designed as a retroreflector assembly, to set a receive signal polarization state and/or a wavelength of a receive signal in response to a received transmit signal and to send the receive signal back as a signal anti-parallel to the transmit signal.
