Abstract

Multifunctional radar is a trend in the future. Employing radar system for high data rate, long range, anti-intercepted communication by using its wide bandwidth, high power and directing property has been a research hotspot nowadays. Thus radar-communication compatible waveform design is a key technique. In this paper, a constant envelope minimum-shift keying orthogonal frequency division multiplexing (CE-MSK-OFDM) modulation scheme is proposed. The modulation scheme can simultaneously mitigate the inherent drawbacks of MSK-OFDM and constant envelope OFDM (CE-OFDM). To make the CE-MSK-OFDM signal have the compatible characters, a suitable system parameterization for operation at 10GHz that fulfills the requirements for both radar and data communications is derived. Then the feasibility of the system parameters and the performance of radar and communications are verified with Matlab simulations. The simulation results reveal that the CE-MSK-OFDM signal can implement the integration of the radar and communications well.
