How it works

Four operations. Built for high-fidelity reconstruction.

NOEMA reduces raw signal data volume without requiring changes to existing recorders, archives, processors, or replay workflows.

01 Intake
Raw signal data enters NOEMA.

Built for high-volume I/Q, radar, RF, and SAR datasets. Runs from defaults, with tuning available when fidelity, throughput, or archive constraints matter.

Raw I/Q dataLevel-0 signal dataRuns from defaults
02 Compress
Create a smaller working archive.

NOEMA compresses signal data according to the statistical profile of each dataset. Compression performance depends on format, entropy, quantization, and fidelity target.

03 Index and store
Keep the compressed archive usable.

Sidecar metadata records file structure, decode locations, reconstruction settings, and verification context so selected files or regions can be accessed later.

04 Reconstruct and verify
Use the data downstream.

Reconstruct full files or selected signal regions for replay, analysis, validation, model-development workflows, or existing ground-processing pipelines. Reconstruction quality is measured with signal-level metrics.

Who it's for

Built for raw SAR archives and processing.

NOEMA helps SAR mission, archive, and processing teams reduce raw I/Q data volume, reconstruct selected signal blocks, and measure reconstruction fidelity against the source.

Satellite in orbit
SAR missions & ground systems
Reduce the raw SAR payload.

Compress Level-0 SAR I/Q into a smaller bitstream with indexed metadata. Evaluate storage and transfer savings alongside your existing ground workflow. Tested on NISAR L-band RRSD products.

SAR-inspired Earth illustration
SAR archives & data centers
Access selected blocks without a full decode.

Use the sidecar index to locate and reconstruct individual signal blocks without decoding the entire bitstream. Keep compressed SAR data accessible for later analysis and reprocessing.

SAR processing & research
Measure fidelity before changing your pipeline.

Compare reconstructed I/Q with the source using SNR, normalized error, and correlation. Tune compression around your fidelity targets, then validate focused-image quality and downstream processing separately.

Technical advantages

Selective reconstruction. Shared representation. Verified compression.

01 SELECTIVE DECODE

Region-based access

NOEMA sidecar metadata enables decoding of specific regions, time windows, or segments without full archive reconstruction, reducing unnecessary data movement during access.

02 SHARED METADATA

Shared codebook

One codebook can serve a batch of files, reducing overhead and keeping reconstruction behavior consistent across the archive.

03 VERIFIED RECONSTRUCTION

Auditability

Sidecar metadata records what was compressed, how it was reconstructed, and which fidelity metrics were measured for every file.
