评审指出第 4、5 节既给出完整模型又称作"预留方向"，读者会 误解定位；同时"AI 方法补偿 nuisance 的重要动机之一"这类 强承诺没有定义 AI 输入输出/训练设置，像未兑现的预告。 本次调整： - sec4:5、sec4:181 "重要动机" / "物理动机" → 改为"自然 接入位置" / "留出接口"，并明确"具体方法不在本笔记范围内" - sec5:6 "新论文方向中'方法适用边界'的核心" → 改为 "本节按这一切换刻画模型接口与方法适用边界" - 摘要"预留多用户与星间时间戳误差两节作为新论文方向" → "以多用户与星间时间戳误差两节给出后续方向所需的模型接口 与初步分析"

\begin{abstract}
|
||
使用通信信号估计来波方向与 Doppler 参数，是通信感知一体化和低轨卫星协作感知中的基础问题。
|
||
本文以学习笔记的方式记录这一问题的递进路径：每节只沿一个维度推进模型，其余维度保持最简形态。
|
||
正文从多快拍单阵列确定信号 \gls{doa} 估计出发，依次引入 Doppler、多星几何，并以多用户与星间时间戳误差两节给出后续方向所需的模型接口与初步分析；最后回到第一篇论文的多帧连续相位结构。
|
||
正文仅写到集中似然的最终形式与有效 \gls{fim} 的 Schur complement 表达式，详细矩阵代入与逐步化简均迁移至附录。
|
||
附录按"是否共享推导框架"组织：单阵列三种 \gls{crb} 合并为附录 D，多星静态模型为附录 E，时间戳误差 \gls{fim} 分析为附录 F，多帧动态模型的连续/独立相位对比为附录 G。
