Abstract
The design of integrated waveform that can simultaneously perform radar and communication function is a key technology in radar and communication integration. This paper proposes a novel integrated radar and communication waveform based on linear frequency modulated (LFM) signal, which performs radar function. Communication data of different channels as well as adjusting data are multiplied with corresponding orthogonal sequences and added together to form communication baseband signal which then modulates the LFM signal. The whole modulating process refers to technologies including 2PSK and CDMA. Theoretical analysis and simulation results demonstrate this novel integrated waveform performs well and meets practical requirements.
