Radar communication integration has become a research hotspot in recent years because it is conducive to improving the utilization rate of equipment hardware resources and spectrum utilization.In view of the current scarcity of spectrum resources and combined with cognitive radio concept,this paper proposes an integrated design of radar and communication based on non-contiguous orthogonal frequency division multiple-xing(NC-OFDM)and estimates the distance and speed of NC-OFDM radar and communication integrated sig-nal measurement target characteristics.The ambiguity function of radar communication integrated signal based on NC-OFDM,the range resolution and azimuth resolution of radar imaging,autocorrelation and bit error rate are analyzed.At the same time,mutual information is selected as the index,and the waveform design is car-ried out by using the main optimization algorithm.The simulation results show that the NC-OFDM radar com-munication integrated signal has better radar detection performance and better wireless communication perform-ance.
