Abstract

Abstract

Radar-communication integration can realize both target detection and wireless communication, so as to reduce electromagnetic interference and improve spectrum utilization. The integrated signal design of radar and communication is the key to the realization of integrated technology. The common radar communication integration signals based on Orthogonal Frequency Division Multiplexing (OFDM) have the problems of frequency offset sensitivity and excessive out-of-band radiation, so they are not suitable for high-dynamic applications. Considering the advantages of Filter Bank MultiCarrier (FBMC) signal with high Doppler tolerance and low out-of-band leakage, the time-frequency locations of radar and communication subcarriers are optimized under the framework of FBMC, and a design method of FBMC comb spectrum radar-communication integrated signal is proposed. Since there is inherent interference between FBMC signal carriers and symbols, which leads to inaccurate channel estimation and is not suitable for fast time-varying channels, an interleaved comb-shaped auxiliary pilot structure is designed to eliminate inherent interference and achieve channel tracking. In addition, the radar complex signal in the integrated signal introduces real interference to the communication signal. A real interference compensation algorithm is proposed based on interference utilization, which is used to restore the communication signal. The simulation results show that under the fast time-varying channel, the designed radar-communication integrated signal has a lower bit error rate and better radar detection performance in the process of high data rate transmission.
