【摘要】 针对现有技术的不足,提出了一种基于随机频率间隔的OFDM-FDA雷达通信一体化波形设计方法。采用较少的脉冲发射多载波的雷达通信一体化信号,在不同阵元间增加了随机频率间隔以便在频域上区分通信数据,从而实现多载波通信信号的传输及频控阵雷达目标成像的功能。仿真结果表明,该一体化信号能够在发射较少脉冲的情况下,有效提高一体化系统的频谱利用率,实现双基地雷达下的数据传输和目标成像功能。更多还原

【Abstract】 Aiming at the shortcomings of the existing technology,an integrated waveform design scheme of OFDM-FDA radar communication based on random frequency intervals is provided.This method uses less pulse to transmit multi carrier radar communication integrated signal,and adds random frequency interval between different array elements to distinguish communication data in frequency domain,so as to realize the transmission of multi carrier communication signal and the function of frequency controlled array radar target positioning.The simulation results show that the integrated signal can effectively improve the spectrum utilization of the integrated system,and realize the data transmission and target imaging functions under the bistatic radar.更多还原
