摘　　要：提出了一种基于时域关联函数的新型测距方案,通过探测信号与接收信号间的关联运算,可以高效提取时间延迟信息,克服了探测器对反射信号时序结构的解析要求。在信号设计中,引入正交信号以减少关联运算的冗余性,并采用连续信号技术以提升时间分辨率和测距精度。数值仿真结果表明,该方法在复杂多路径传播和低信噪比条件下表现出卓越的测距性能,成功实现了对单点及多目标场景的高精度测距,验证了其在复杂环境中的适用性与可靠性。这一方案为测距技术提供了全新的理论框架和技术路径,特别适用于高精度、多目标、动态场景的应用需求。A novel ranging scheme based on temporal second-order correlation function is proposed,enabling efficient extraction of time delay information through correlation operations between the detection and reflected signals without relying on the detector’s resolution of the reflected signal’s temporal structure.Orthogonal signals are introduced in the signal design to reduce redundancy in correlation operations,while continuous signal techniques are employed to enhance time resolution and ranging accuracy.Numerical simulations demonstrate the method's exceptional performance in complex multi-path propaga-tion and low signal-to-noise ratio conditions,achieving high-precision ranging for both single-point and multi-target scenarios.This approach establishes a new theoretical framework and technical pathway for ranging technology,particularly suited for high-precision,multi-target,and dynamic scene applications.
