feat: PSI 잔차높이 Δh 역산 — 산란체 실고도(순수 InSAR) - #7
Merged
Conversation
SNAP 간섭도가 지형위상을 제거하므로 남은 LOS = 잔차지형위상(Δh)+변형+대기. 각 PS 에서 B⊥ 상관성분(Δh)을 변형(시간상관)과 동시 최소자승 분리(SARvey/StaMPS DEM-오차+속도 결합추정 핵심). Δh + DEM 표고 = 산란체 절대고도(데크 산란체는 SRTM 지형보다 높음). - insar/psi_height.estimate_residual_height(): 점별 [Δh, v, offset] LS. σ_Δh(정밀도)·잔차·절대고도. - gltf_export z_source='psi': 산란체 실고도(DEM+Δh)를 glb Z 로. - CLI: --gltf-z-source psi --gltf-bperp(B⊥ JSON) --gltf-dem. 검증(왕복): 알려진 Δh(±40m)·v(±10) 주입→복원 — Δh 회귀 기울기 1.06(무편향)·오차 std 13.9m = 이론 σ_Δh 13.1m 일치, v 분리 r=0.99. 실 CHYG: σ_Δh 14.1m(B⊥스프레드 54m 한계), 농촌이라 Δh~0(올바른 null). 테스트 3(왕복 무편향·0높이 null·gltf psi). 코어 venv 584 passed/0 failed. 한계(정직): 정밀도 σ_Δh ∝ 노이즈/(B⊥스프레드·√M). CHYG 54m→±14m(데크·타워는 잡히나 미세형상 거칠다). 더 넓은 B⊥·SARvey PS선별로 개선. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01EN8ND36zFNxn8mDhVBSgWe

SNAP 이 지형위상 제거 → 남은 LOS 의 B⊥ 상관성분(Δh)을 변형과 동시 LS 분리. Δh+DEM=산란체 절대고도.
--gltf-z-source psi. 왕복검증: Δh 주입→복원 기울기 1.06(무편향)·오차=이론 σ_Δh, v 분리 r=0.99. 실 CHYG σ_Δh 14.1m(B⊥ 54m 한계, 농촌 Δh~0=null). 584 passed/0 failed. 정밀도 개선은 넓은 B⊥·SARvey PS선별.🤖 Generated with Claude Code
