Integrated Radar and Communication Based on Multicarrier Frequency Modulation Chirp Signal


Abstract:
Integration of radar and communication on the electronic war platform is an effective method to reduce their volume, electromagnetic interference. In allusion to mutual interference and incompatible issue between suitable wareforms design of integrated radar and communication, following the principle of signal sharing, integration of radar and communication system and the correspondence processing scheme is presented based on FM orthogonal multicarrier chirp signal. First, based on wideband ambiguity function, the characteristics of the multicarrier integrated signal are analyzed in detail. The system performance and signal processing of integrated signal are analyzed. Simulation results and theoretical analysis show that the integrated signal can satisfy conventional radar detection and have low bit error rate under 20% rate of spectrum overlapping.

Key words:Integration of radar and communication,Signal sharing,Multicarrier,Wideband ambiguity function,Spectral efficiency
