During high-speed maneuvers, aircraft experience rapid distance changes, necessitating high-frame-rate ranging for accurate characterization. However, existing optical ranging technologies often lack simplicity, affordability, and sufficient frame rates. While dual-station triangulation enables high-frame-rate distance calculation via geometry, it suffers from complex and costly deployment. Conventional laser rangefinders are limited by low repetition rates. Single-photon ranging, using high-frequency low-energy pulses and detecting single reflected photons, offers a promising alternative. This study presents a kilohertz-level single-photon ranging system validated through civil aviation field tests. At 1000 Hz, relative distance, velocity, and acceleration were successfully captured. Simulating lower frame rates (100 Hz, 50 Hz, 10 Hz) via misalignment merging revealed standard deviations of 0.1661 m, 0.2361 m, and 0.2683 m, respectively, indicating that higher frame rates enhance distance measurement reproducibility. Error analysis against the 1000 Hz baseline further confirms that high-frame-rate ranging improves precision when monitoring high-speed maneuvers.
在高速机动过程中，飞机会经历快速的距离变化，因此需要高帧率测距来进行精确表征。然而，现有的光学测距技术往往缺乏简单性、经济性和足够的帧率。虽然双站三角测量法能够通过几何方法进行高帧率距离计算，但它存在部署复杂且成本高昂的问题。传统激光测距仪受限于低重复率。单光子测距利用高频低能量脉冲并检测单个反射光子，提供了一种很有前景的替代方案。本研究展示了一种通过民航现场测试验证的千赫兹级单光子测距系统。在1000赫兹时，成功捕获了相对距离、速度和加速度。通过错位合并模拟较低帧率（100赫兹、50赫兹、10赫兹），结果显示标准偏差分别为0.1661米、0.2361米和0.2683米，这表明更高的帧率可提高距离测量的可重复性。相对于1000赫兹基线的误差分析进一步证实，在监测高速机动时，高帧率测距可提高精度。
