【摘要】：為了最大程度地利用資源和減小電磁干擾,電子戰(zhàn)平臺的雷達通信一體化設(shè)計有著尤為重要的意義。針對通信中成熟應(yīng)用且在雷達中有較好前景的正交多載頻波形,提出直接序列擴頻正交頻分復(fù)用(OFDM)進行雷達通信一體化的想法。給出了實現(xiàn)方法,重點對該一體化信號模糊函數(shù)進行求解和分析,指出增加子載波數(shù)目信號分辨性能更佳;隨機的信息流僅對模糊函數(shù)的鄰道干擾項造成影響,為進一步優(yōu)化一體化信號旁瓣性能提供了理論依據(jù)。最終的仿真結(jié)果和性能分析表明,該一體化信號能夠?qū)崿F(xiàn)雷達通信一體化的目的。
[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.
