We show that injecting parametric-amplifier designfacts into field SIGINT—rpm notch/pole locations, stopbands,and pump-locked idler relations from three-/four-wave mixing—cuts false positives while preserving recall. We anchor indeployed hooks (_load_atl_design, _label_atl_band,_mixing_relations, annotate_signal_with_atl,process_atl_alerts) and report ablations over frequencytolerance (ppm) and the length of the recent-frequency FIFOused to hypothesize idlers. Code produces a press-once PDFwith ROC/PR curves and parameter … Continue reading Design-Informed RF Event Detection with ATL/TWPA Priors
