Feature Description

⛰️ NASA SRTM Terrain Masking Real elevation data (90m resolution) — 72-ray horizon

scan algorithm, blast zones blocked by actual mountains

🌍 Global SRTM Coverage ~5700 tiles, full world 60°S–60°N offline cache (srtm_cache/)

🔭 Horizon Scan Algorithm For each of 72 rays: scans terrain profile, detects shadow zones behind ridges

📐 Asymmetric Blast Zones Zones expand freely through valleys, contract against mountain faces

🏔️ Elevation Display Impact point elevation shown in panel (e.g. ⛰️ SRTM (1340m n.p.m.))

🌬️ Fallout Polygon Fix Corrected azimuth→lat/lon conversion — proper wind-aligned elliptical plume

🚀 Hybrid Ballistic Model SRBM: Euler+ISA physics; ICBM/IRBM: analytic formulas calibrated to SIPRI/CSIS data

📊 Realistic ICBM Data Sarmat 9000km: 29.9min, apogee 1080km ✓ / MM-III 8000km: 28.4min, apogee 960km ✓

Source Application

Glasstone & Dolan (1977) Nuclear blast radii — fireball, overpressure zones, thermal burns

NATO FM 6-40 Conventional HE blast zones

ISA Standard Atmosphere Air density by altitude for trajectory simulation

Haversine formula Accurate great-circle distance

Euler integration (dt=1.0s) SRBM trajectory with air drag, Coriolis deflection

SIPRI / CSIS / FAS ICBM calibration data — apogee ratios, flight times

NASA SRTM Real elevation sampling for terrain masking horizon scan

Nuclear Physics — Glasstone & Dolan (1977) Fireball: r = 100 × W^0.41 [m] Heavy (20psi): r = 290 × W^0.33 [m] Light (5psi): r = 690 × W^0.33 [m] Burns (1°): r = 2200 × W^0.41 [m]

Hybrid Ballistic Model SRBM / short MRBM (dist < maxRangeSim): → Full Euler+ISA simulation → FindElevationAngle bisection [45°–85°] → SimulateFlightTime with ISA density layers

ICBM / IRBM (dist > maxRangeSim): → Analytic formulas (calibrated SIPRI/CSIS/FAS): angle = 45° apogee = dist × apogeeRatio (0.06–0.13 by range) tof = dist / (v0 × 0.70) ← v_avg = 70% burnout velocity

Validation: ATACMS 165km, v0=1766: tof=134s (2.2min), apogee=10km ✓

Iskander 500km, v0=2203: tof=324s (5.4min), apogee=40km ✓ Sarmat 9174km, v0=7300: tof=1795s (29.9min), apogee=1101km ✓ MM-III 8000km, v0=6700: tof=1706s (28.4min), apogee=960km ✓

SRTM Terrain Masking — Horizon Scan Algorithm For each of 72 ray directions (0–360°): elev0 = SRTM elevation at impact point max_horizon = -999°

For each sample s (0 to n_samples): d = max_blast_radius × s / n_samples point = impact + d × direction elev = SRTM.get_elevation(point) angle = atan2(elev - elev0, d) ← elevation angle from impact

if angle > max_horizon: max_horizon = angle ← new horizon line elif max_horizon > 3° and angle < max_horizon - 3°: shadow_dist = d ← terrain blocks wave here break

ray_factor = shadow_dist / max_blast_radius (0..1)

Polygon: each zone radius × ray_factor × small noise Result: asymmetric polygon — contracted against ridges, expanded through valleys
