【摘要】:为了最大程度地利用资源和减小电磁干扰,电子战平台的雷达通信一体化设计有着尤为重要的意义。针对通信中成熟应用且在雷达中有较好前景的正交多载频波形,提出直接序列扩频正交频分复用(OFDM)进行雷达通信一体化的想法。给出了实现方法,重点对该一体化信号模糊函数进行求解和分析,指出增加子载波数目信号分辨性能更佳;随机的信息流仅对模糊函数的邻道干扰项造成影响,为进一步优化一体化信号旁瓣性能提供了理论依据。最终的仿真结果和性能分析表明,该一体化信号能够实现雷达通信一体化的目的。
[Abstract]:In order to maximize the utilization of resources and reduce electromagnetic interference, the integrated design of radar communication for EW platform is of great significance. The idea of radar communication integration by direct sequence spread spectrum orthogonal frequency division multiplexing (OFDM) is put forward. The realization method is given, the ambiguity function of the integrated signal is solved and analyzed emphatically, and it is pointed out that the resolution performance of the signal with increasing the number of sub-carriers is better. The random information flow only affects the adjacent channel interference term of the ambiguity function, which provides a theoretical basis for further optimization of the sidelobe performance of the integrated signal. The final simulation results and performance analysis show that, The integrated signal can realize the purpose of radar communication integration.
