Abstract
A multistatic radar surveillance system includes transmitter elements and receiver elements arranged according to a zone to be monitored, and a command and control unit that configures the elements and collects information relating to objects detected by the receiver elements. Each transmitter element transmits a signal, the bandwidth of which is substantially equal to the totality of a frequency band B allocated to the system. Each transmitter element transmits a common waveform to all of the transmitter elements, and the waveform is modulated by a binary signal specific to the element in question, this signal allowing each of the receiver elements receiving a signal to identify the transmitter element at the source of this signal. The coding applied to the waveform is defined so that the spread spectrum caused to the signal transmitted by the latter does not exceed the frequency band B allocated to the system.
