Status

Draft for SRR — skeleton

This DPM is the engineering processing model of sar-processor: the end-to-end transformation of downlinked raw Level-0 SAR instrument source packets into L1 SLC / L1 GRD products, decomposed into processing modules with their data flows, parameters and breakpoints. ID schemes: DPM-M-* modules, DPM-PR-* products, DPM-ADF-* auxiliary data files, DPM-PRM-* parameters, DPM-BKP-* breakpoints. Content TBD (PDR).


<1> Introduction#

Engineering counterpart of the ATBD: same stage chain, expressed as modules with concrete data interfaces. TBD (PDR).

<2> Applicable and reference documents#

Per SDP <2>. TBD (PDR).

<3> Processing model overview#

End-to-end flow diagram (mermaid) L0 → SLC → GRD; module list DPM-M-* mirrors the ATBD stage set (<4.1>–<4.7>). TBD (PDR).

<4> Modules (DPM-M-*)#

Per module: function, inputs (DPM-PR-* / DPM-ADF-*), outputs, parameters (DPM-PRM-*), breakpoints (DPM-BKP-*). TBD (PDR pending SentiWiki S1 ingest).

<5> Products and auxiliary data#

Product tree (DPM-PR-*): TBD S01 SAR product type codes fixed in ICD at PDR. ADF set (DPM-ADF-*): calibration constants, antenna patterns, orbit files. TBD (PDR).

<6> Traceability#

REQ-*DPM-M-* → SDD components in the traceability matrix. TBD (CDR).
