Public engineering surrogate
This is a public engineering-surrogate propagation emulator. It estimates atmosphere/AO/coupling penalties under declared assumptions and validation limits. It is not mission-certified and does not reproduce internal NASA/JPL pipelines.
Wave-Optics / Atmosphere / AO Surrogate
Penalty / Strehl / coupling distribution emulator over the reduced turbulence/coupling manifold, atmosphere/AO regime chamber, threshold layer, and safety layer. Public scenario anchors only.
Headline penalty numbers under the public scenario anchor. Fade probability gauge, percentile penalties (dB), dominant impairment, and escalation flag.
Fade probability P_fade
threshold 6.0 dB
Headline numbers
| Fade probability P_fade | — |
| Median penalty p50 | — |
| 95th percentile p95 | — |
| Median Strehl S_50 | — |
| Median coupling eta_50 | — |
| Dominant impairment | — |
| High-fidelity escalation | — |
| Escalation reason | — |
Nested scenario form: optical, atmosphere, AO, receiver. Defaults come from the selected public scenario anchor.
Regime presets and derived atmosphere/AO quantities at the active scenario. Cn²(h) hint is shown when an outer-scale profile is supplied.
Regime presets
Quick load: standard atmosphere/AO presets that overwrite the atmosphere + AO blocks of the active scenario.
Derived quantities (deterministic)
| Airmass X = sec(zenith) | — |
| Fried r_0 at operating lambda | — |
| D_r / r_0 | — |
| Atmospheric loss (single-pass dB) | — |
| Aerosol attenuation | — |
| Strehl S (nominal, from residual WFE) | — |
| Coupling eta_coup (nominal) | — |
| Total deterministic penalty | — |
Cn²(h) hint
Per-input distribution picker. Supported distributions: fixed, normal, lognormal, uniform, triangular, empirical. Correlations are recorded but not yet sampled.
Correlations
Independence is assumed across inputs unless a correlation list is supplied. The MVP records correlations but does not yet draw correlated samples.
Histogram of propagation penalty (dB) over the Monte Carlo run, and the cumulative distribution. ~50 bins.
Separate distributions for the AO Strehl ratio S and the fiber/detector coupling efficiency eta_coup, sampled across the Monte Carlo run.
Probability of each canonical impairment class across the Monte Carlo samples. The dominant impairment card shows which mechanism in the reduced turbulence/coupling manifold was active most often.
Dominant impairment
2D r_0 vs pointing-jitter heatmap (mean penalty dB)
Sweep at fixed other inputs; intended as a coarse design-space hint, not a high-fidelity surface.
Tornado chart of penalty sensitivity to each input (delta penalty per fractional input change). Largest-magnitude bars are the most-load-bearing inputs.
Dominant uncertainty contributor
Escalation logic flags scenarios where the public engineering surrogate alone is insufficient and a high-fidelity wave-optics model is recommended.

Recommended high-fidelity model
The wave-optics surrogate inherits the lab-wide validation page. Method sanity tests below; full report under the link.
Benchmark dataset (optional)
Reproducible wave-optics certificate. The deterministic result_hash pins inputs + constants + formulas + outputs. The receipt_hash adds the export timestamp.

——Show research mapping (research id - public engineering name)
The wave-optics surrogate runs over a constraint-compression framework. The public UI uses these engineering names:
| Research id | Public engineering name | Role |
|---|---|---|
K_6 | reduced turbulence/coupling manifold | Limiter manifold over the propagation penalty |
F_plus | atmosphere/AO regime chamber | Regime classifier (which limiter is active) |
L_threshold | threshold layer | Penalty-vs-budget test |
L_safety | safety layer | False-safe risk + escalation projector |
x, ⊕, ⊗ | full geometry map | Active-branch geometry of the propagation problem |
The active-branch architecture is used as a constraint-compression framework, not as a claim that high-dimensional physics is required for standard atmospheric / AO engineering.
