Shared waveform design is the key to maximizing the resource utilization efficiency of radar and communication integration systems.Aiming at the problem that the existing integrated waveform multi-ple access communication function is deficient,a radar communication integrated waveform based on the OPPERMANN sequence spread spectrum is designed.The OPPERMANN sequence is utilized to assign weights to the radar pulse signal,and to modulate the communication signals of multiple downlink users in sub-pulse.The spectrum of the communication signals of different users and radar signals are spreaded by orthogonal OPPERMANN sequence to realize the dual function of radar and communication.The theoreti-cal analysis and simulation experiment results show that the designed integrated waveform makes radar and communication signals share the same frequency band,it can not only communicate with multiple downlink users at the same time but also has different types of ambiguity functions,which can meet the waveform design requirements of the radar system in target detection and target tracking scenarios.
