本文以一份可持续扩展的推导笔记为目标，先在单阵列确定信号与随机信号模型下整理经典 \gls{doa} 估计、DoA--Doppler 联合估计及其 \gls{crb}，再将模型推进到单用户多星协作场景。 - 多星主线采用统一的全局方向参数 $\boldsymbol\xi=[\alpha,\beta]^\Tran$ 与参考星链路归一化 Doppler 参数 $\nu_{\mathrm{ref}}$，先建立静态 DoA--Doppler 基线模型，再引入多帧索引、Doppler rate $\dot\nu_{\mathrm{ref}}$ 和跨帧连续相位结构，进一步比较 relaxed 连续相位模型与独立相位基线模型的信息差异。 - 在此基础上，本文还给出 DoA--Doppler--delay 扩展和相应附录推导，使单阵列基础、多星主线、对比模型与 \gls{crb} 分析在同一符号体系下衔接。 + 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，并预留多用户与星间时间戳误差两节作为新论文方向；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。 \end{abstract} \input{parts/preface.tex} \input{parts/02-modeling.tex} -\input{parts/detDoaEst.tex} -\input{parts/stoDoaEst.tex} -\input{parts/detDoaDopplerEst.tex} -% \input{parts/stoDoaDopplerEst.tex} -\input{parts/multiArrayStoDoaEst.tex} -\input{parts/multiArrayStatDetDoaDopplerEst.tex} -\input{parts/multiArrayDynDetDoaDopplerEst.tex} -\input{parts/multiArrayDetDoaDopplerDelayEst.tex} -% \input{parts/98-future work.tex} +\input{parts/sec1_singleArrayDoa.tex} +\input{parts/sec2_singleArrayDoaDoppler.tex} +\input{parts/sec3_multiSatSingleUser.tex} +% \input{parts/sec4_multiSatMultiUser.tex} % 阶段 5 新增 +% \input{parts/sec5_timestampError.tex} % 阶段 5 新增 +\input{parts/sec6_multiFrameCp.tex} +% \input{parts/sec7_beamforming.tex} % 预留，本次不展开 \appendix \renewcommand{\thesection}{附录~\Alph{section}} diff --git a/parts/detDoaEst.tex b/parts/sec1_singleArrayDoa.tex similarity index 100% rename from parts/detDoaEst.tex rename to parts/sec1_singleArrayDoa.tex diff --git a/parts/detDoaDopplerEst.tex b/parts/sec2_singleArrayDoaDoppler.tex similarity index 100% rename from parts/detDoaDopplerEst.tex rename to parts/sec2_singleArrayDoaDoppler.tex diff --git a/parts/multiArrayStatDetDoaDopplerEst.tex b/parts/sec3_multiSatSingleUser.tex similarity index 100% rename from parts/multiArrayStatDetDoaDopplerEst.tex rename to parts/sec3_multiSatSingleUser.tex diff --git a/parts/multiArrayDynDetDoaDopplerEst.tex b/parts/sec6_multiFrameCp.tex similarity index 100% rename from parts/multiArrayDynDetDoaDopplerEst.tex rename to parts/sec6_multiFrameCp.tex
