摘要: 为解决更高精度及更多维度的无源目标探测与导航定位问题,利用量子压缩与纠缠传感装置构建了一个基于量子照射模型的单站时差与方位角目标定位系统,研究了基于量子照射的精密测时与测角估计方法,并探讨了基于时差与方位观测量的量子目标空间定位性能。以激光雷达系统的平面目标定位任务为例,研究了传输系数与压缩因子对空间目标定位精度的影响,展示了目标空间定位任务中的量子优越性。

Abstract: To solve the challenges of passive target detection and nagivation localization with enhanced precision and multi-dimensionality, this study constructed a single-station quantum illumination model that employs quantum squeezing and entanglement-sensing devices for time delay and azimuth angles. An in-deep investigation has been conducted into the estimation methods for precise time delay and azimuth angle measurement of quantum illumination signals, and the potential of quantum positioning based on time-differences and azimuth observations has been explored. Taking the task of planar target localization of a LiDAR system as an example, we investigate the influence of transmission coefficient and squeezing factor on spatial target localization accuracy. The results reveal the quantum superiority in target spatial localization tasks.

Key words: quantum illumination, target localization, entangled state, squeezing factor, geometric dilution precision
