Reproducibility data and code for altitude-dependent radar detection-range curves Rmax(H)

Digitized radar-diagram nodes, complete Rmax(H) arrays on a 0.1-km altitude grid, a transparent Python translation of the VBA MyCalcL procedure, control nodes, verification data, and publication figures. The independent implementation reproduces all 601 cached VBA values for 79K6 and for both 5N84A beams with a maximum absolute difference of 0.0 km.

The source code in the code/ directory is released under the MIT License. Version 2 accompanies the revised manuscript AJSE-D-26-11835R1. It adds Python code and full-precision outputs that reproduce Tables 1–12 and the data underlying Figs. 1–10: fixed-network station coordinates, interval lower bounds over the 10–30 km altitude band and along the ballistic trajectory, the correlated-update model, RCS-fluctuation and map-projection results.
