摘要
Abstract
A new range super-resolution method is proposed for the integration of orthogonal frequency division multiplexing(OFDM) radar and communication.And an OFDM pulse pattern is designed to achieve long distance ranging.In the transmitted pattern,the communication function is realized within the pulse,and the possibility of using radar beam side-lobes to transmit communication signal is discussed.During the coherent processing interval,the randomness of the communication modulated information is applied to solve range ambiguity,then the range sparse reconstruction model is formed after communication information is compensated,and finally,the L1-SVD method is applied to obtain the super-resolution estimation of ranges.Theoretical analysis and simulation results indicate that the proposed method can enhance the range resolution and guarantee the communication function.关键词
