Waveform design for integration of MIMO radar and communication based on orthogonal frequency division complex modulation

The integration technology of radar and communication is an effective way to realize resource platform sharing, system advantages complementation and comprehensive performance improvement. Aiming at the shortcomings of the current integrated waveform, an integrated waveform for MIMO radar and communication is proposed in the paper based on orthogonal frequency division complex modulation (OFDCM), which is of favourable performance on the radar and communication. Theoretical analysis and simulation experiments show that the designed waveform not only acquires excellent communication performance with high transmission rate and large transmission capacity, but also features satisfactory performance for radar targets detection such as wide bandwidth, interference rejection, low interception and high doppler tolerance
