基于正交频率调制的雷达通信共享信号设计
Design of Radar and Communication Shared Signal Based on Orthogonal Frequency Modulation
摘要
Abstract
To improve the ambiguity function performance and Doppler robustness of radar communication shared signal,a single carrier and constant envelope radar communication shared signal based on orthogonal frequency modulation is designed.Firstly,the signal phase is modulated,which is divided into frequency modulation term and communication modulation term;Secondly,the idea of orthogonal modulation is used,the time-frequency function of the frequency modulation term is designed as a linear combination of orthogonal frequency modulation terms;Then,communication modulation is achieved by modulating the coefficients of each orthogonal frequency modulation term;Finally,the orthogonality of trigonometric function is utilized to determine the demodulation steps.The performance analysis shows that the designed signal has such advantages as thumbtack fuzzy function,low cross-fuzzy function and resistance to Doppler fading,etc.The simulation results show that the designed radar communication shared signal also has better radar detection performance at high data rate communi-cation,the effectiveness and the feasibility of the designed signal are proved.关键词
