Abstract :
In this paper, the benefits of OFDM waveforms are analyzed for multistatic radar systems, where several radar stations cooperate in the same frequency band. The signal is coded over a 2D pattern, in the time and the frequency domains, using orthogonal Golay complementary sets derived from Reed-Muller codes. Binary data are also encoded in the signal. The obtained ambiguity and cross-ambiguity functions show that the OFDM signal structure is well adapted for radar applications. Transmitted waveforms have relatively low interference and sidelobe levels in the range and Doppler axis.
