ABSTRACT:
In a device for bistatic radar applications, at least two spaced-apart radar sensors having separate carrier-frequency oscillators are provided, which do not require phase synchronization. The pulse modulation is carried out time-synchronously for all transmitter and receiver pairs. The cross-echo signals can be analyzed in an analyzing unit, in which a mixing of the transmitted and received signals takes place.
