证伪线与实验建议

  1. 证伪线:当 EFT 参量 → 0 且 A_ct—BW_ct—Σ_ct,mp—Bias_ρ—τ_rms 的协变关系消失,同时主流组合模型在全域满足 ΔAIC<2、Δχ²/dof<0.02、ΔRMSE≤1%,则本机制被否证(当前最小证伪余量 ≥ 3.6%)。
  2. 实验建议
    • 相图绘制:在 “SNR × 反射几何” 平面绘制 A_ct、Bias_ρ、τ_rms 相图,提取阈值边界。
    • 网络整形:调整反射体/遮挡布局与材料,检验 ζ_topo 对 BW_ct、Bias_ρ 的线性响应。
    • 跨平台同步:GNSS/UWB/mmWave/LiDAR 同步时间基(≤100 μs),提升 CCI 估计精度。
    • 环境抑噪:稳温/抗振/EM 屏蔽以量化 k_TBN 对公共项底噪的影响。
