探通一体化是雷达对抗复杂电磁干扰的一种重要手段,其中基于线性调频(LFM)信号的共享信号设计是实现探通一体化的关键技术之一。文中提出了一种LFM 信号相位/ 调频斜率调制的探通一体化共享信号设计方法,通过设计附加相位或调频斜率以实现基准LFM 信号的调制,构建一个具有良好自相关和互相关性能的共享信号库。仿真给出了共享信号设计参数的选取依据,并分析了其探测及通信性能,证明了其在目标检测及通信应用中的优势。

Radar-communication integration is an important way to resist to the complicated electromagnetic interference, in which the design of the integrated signal, based on linear frequency modulation (LFM) signal, is one of the key technologies to the radar-communication integration. Based on phase/ chirp rate modulated LFM, a design method of integrated radar-communication signal is proposed in this paper. Focusing on the standard LFM modulated by additional phase or chirp rate, a bank of signals, which enjoy satisfactory autocorrelation and cross-correlation characteristics, are finally established. Basis for the parameter selections in the design and performance analysis in terms of radar detection and communication scenario are provided in simulation results, which confirms the advantages of the designed signal in the applications of detection and communication.
