Abstract

fetched live from OpenAlex

Signal band and Doppler band are very large in order to realize precise imaging of high-resolution spaceborne spotlight SAR.At the same time normal imaging methods can not satisfy the radar system coverage performance and the precision of imaging.This paper offers a kind of high precision imaging method for high-resolution(0.3m) space borne spotlight SAR.This method utilizes Deramp Chirp Scaling and the cubic correction method,and offers a Deramp Chirp Scaling algorithm with cubic correction for space borne spotlight SAR.The method proved effective by the simulation.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
