Abstract: An apparatus comprising one processor and one memory including computer program code to: generate at least one sample corresponding to at least one radar/non-radar signal; form at least one spectrogram using time and frequency domain characteristics of the sample; wherein the spectrogram is formed via subdividing an observation window of the sample into time slots of a given duration, computing a power spectral density for a subset of the time slots having a higher determined energy relative to other time slots, and combining one or more computed power spectral densities of the subset; pass the spectrogram to a model to detect a presence of the radar signal and classify the radar signal as either interference/noise or radar present, and estimate a bandwidth of the detected radar signal; and determine the radar signal to be in-band or out-of-band relative to a shared spectrum hand, based on the estimated bandwidth.
