TRANSMITTER DETECTION IN SHARED SPECTRUM BAND - A simplified explanation of the abstract

This abstract first appeared for US patent application 18566979 titled 'TRANSMITTER DETECTION IN SHARED SPECTRUM BAND

The apparatus described in the patent application includes a processor and memory with computer program code to analyze radar/non-radar signals and classify them as interference/noise or radar present.

Utilizes time and frequency domain characteristics to generate samples of radar/non-radar signals.
Forms spectrograms by subdividing observation windows into time slots and computing power spectral densities.
Passes the spectrograms to a model to detect radar signals, classify them, and estimate their bandwidth.
Determines if the radar signal is in-band or out-of-band relative to a shared spectrum hand based on the estimated bandwidth.

Potential Applications: - Radar signal detection and classification in various industries such as telecommunications, defense, and aerospace. - Spectrum management and interference mitigation in wireless communication systems.

Problems Solved: - Efficient detection and classification of radar signals in complex signal environments. - Accurate estimation of radar signal bandwidth for spectrum sharing applications.

Questions about the technology: 1. How does this technology improve radar signal detection in comparison to traditional methods? 2. What are the potential implications of accurate radar signal classification in spectrum management and sharing scenarios?

Original Abstract Submitted

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.
