These \u201cfailure rims\u201d occupy narrow regions<br>of a high-dimensional parameter space spanned by signal-to-noise ratio (SNR), frequency offset \u2206f, amplitude modulation depth (AM) and the Q factor of the analog front end. Mapping such rims with exhaustive sweeps is prohibitively expensive. This paper demonstrates<br>how uncertainty-seeking acquisition coupled with surrogate models can be used to chart failure<br>boundaries efficiently. A synthetic benchmark illustrates failure rims in three parameter planes:<br>SNR \u00d7 \u2206f, SNR \u00d7 AM, and \u2206f \u00d7 Q. Contour plots reveal how ghost hit rates rise and true<br>hit rates collapse along distinct ridges, providing actionable insights for tuning RF pipelines.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In RF demodulation pipelines, system failure is often characterised by the emergence ofghost modes and a collapse of true detections.
