Abstract

Systems and methods for combined parallel processing of spectral information in a radio frequency environment. One example method includes controlling, with an electronic processor, a wideband receiver coupled to a receive path to scan a band of interest. The method includes receiving, from the wideband receiver, wideband scan data for the band of interest. The method includes identifying, based on the wideband scan data, a spectral region including a signal of interest. The method includes controlling, with the electronic processor, a narrowband receiver coupled to the receive path in parallel with the wideband receiver to collect a sample of the signal of interest.

Dependent claims

A system for analyzing radio frequency spectrum, the system comprising:

a wideband receiver coupled to a receive path;
a narrowband receiver coupled to the receive path in parallel with the wideband receiver;
and
an electronic processor, coupled to the wideband receiver and the narrowband receiver and configured to
control the wideband receiver to scan a band of interest;
receive, from the wideband receiver, wideband scan data for the band of interest;
identify, based on the wideband scan data, a spectral region including a signal of interest;
control the narrowband receiver to collect a plurality of samples of the signal of interest over a period of time;
and
for each of the plurality of samples,
measure a time-variant signal characteristic;
compare a measured value for the time-variant signal characteristic to a predetermined threshold;
and
when the measured value exceeds the threshold, transmit an alert message to an external device.
