摘要
基于线性调频的一体化波形具有优良的雷达性能,但是通信吞吐率较低。变通信速率的策略被设计用于提高一体化波形的通信吞吐率。研究发现调制在一体化波形中部的数据对雷达性能影响较小,因此提出在保持头部和尾部的通信数据速率不变的前提下,提高中部数据的发送速率以增加吞吐率。仿真结果表明:设计的变速率一体化波形与恒速率一体化波形相比,能提高50%的通信吞吐率;和恒速率波形相比,其雷达检测性能和雷达波形模糊函数性能都没有降低。
The integrated waveform based on LFM signal has good radar performance,but its communication throughput is low.The variable communication rate strategy is designed to improve the throughput of the integrated waveform.It is found that the modulation data in the middle of the integrated waveform has little effect on the radar performance.Therefore,we propose to increase the throughput rate by increasing the transmission rate of the middle data while keeping the communication data rate of the head and tail unchanged.The simulation results show that compared with the constant rate of integrated waveform,the designed variable rate of integrated waveform can improve the communication throughput by 50%.Compared with the constant rate waveform,the radar detection performance and the radar waveform ambiguity function performance are not reduced.
