Abstract

The invention refers to a transponder device including a receiver unit (1), a processing unit (3) and a transmitter unit (5). The receiver unit is arranged to receive a radar pulse including an interrogation signal. The processing unit includes first means (32, 33) arranged to interpret the interrogation signal, second means (34) arranged to determine if a response is to be transmitted and to generate a response depending on said determination, and third means (35, 36) arranged to generate a response signal from said response. The transmitter unit includes a mixer (52) for generating a response radar pulse and a frequency manipulator (53) for shifting the frequency of the generated response radar pulse. The transmitter unit (5) is arranged to transmit the frequency shifted response radar pulse.
