Orthogonal multicarrier phased coded signal for netted radar systems

Abstract

Orthogonal multicarrier radar waveforms have been designed for netted radar systems, where several radar stations are active simultaneously. The waveforms are phase-coded using orthogonal Golay complementary sets, derived from Reed Muller codes. These codes constrain the PMEPR of the signal to a maximum a 3 dB. Besides, ambiguity functions and cross-ambiguity functions with low sidelobes have been obtained. The possibility to encode data relative to the transmitter configuration (position, direction of the beam,...) in the radar waveform is also demonstrated.
