A Novel Integrated Waveform for the Radar-Communication Integration System

In the radar and communication integration system based on the linear frequency modulation (LFM), the communication information has great influence on the ambiguity function and the communication performance. To solve this problem, we propose a novel integrated waveform, where we employ the LFM signal combining with the time division technology as carriers to carry the communication information. Then we analyze its ambiguity function, matched filter design, distance resolution and BER performance. Theoretical analysis and simulation results demonstrate this novel integrated waveform performs well and meets practical requirements.
