摘要
The present invention relates to a kind of active transponder, in particular in polarization sensitive synthetic aperture radar system or SAR1, comprising: receiving antenna (20), for receiving the first rf-signal modulation according to first a succession of one or more first pulses; Separation means (3), including two outputs, in the first radiofrequency signal of each output; Second processing device (7,8,9,10,11,12) is connected to the first output (3) separation means, can generate at least one yard of synchronous and the first pulse; Signal generation apparatus (4) be connected to the second output separation means (3) and with second processing device (7,8,9,10,11,12), the second rf-signal modulation can be generated by the second processing means (7,8,9, (70, (71, (72 of at least one code building; With transmitting antenna means (30), the second radiofrequency signal can be sent; It is characterized in that, the second processing device (7,8,9,10,11,12) have the ability generate, each first pulse, one or more pulse per second (PPS)s of a sequence, at least one described code be it is synchronous, with the second pulse.
