Radar and communication integration based on complete complementary codes

Abstract

In modern electronic warfare, integration of radar and communication plays an important role in maximising resource utilisation and reducing electromagnetic interference, especially for the integrated waveform design technology based on signal sharing. Here, the authors introduce polyphase complete complementary codes (CCC) into the integration of spread spectrum radar and communication. According to the correlation property of CCC, they deduce the analytical expression of the ambiguity function of CCC and introduce the integration system based on CCC. Simulation results show the superiority of CCC in correlation, which means that it can be used as a spread spectrum sequence in the radar and communication integration field.
