A method described by Sean Gorman and implemented by user @auonsson uses jammers' interference detected by radar bearings to compute center positions and uncertainties of jammers. The analysis identified several likely radar jammers around Ukraine and Kaliningrad by combining bearings over multiple satellite passes. Calibration against a known jammer near Shiraz, Iran, showed a positional error of 2.5 km. Detection thresholds were raised to reduce false positives. Data used were from NISAR satellite beta imagery, last collected in January 2026, with limited coverage and lacking optimal perpendicular passes. The method relies on large data files (14GB each), and Google Earth KML files were created for visualization. Although exact position accuracy over the Baltics is uncertain, detections near Kaliningrad were reported with a CEP (Circular Error Probable) of 95 meters plus 50 meters.
