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. ContentTBD (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).
