St. Scientists from St. Petersburg State Electrotechnical University “LETI” are creating a device for radio monitoring of signals in a wide frequency range. The new spectrum analyzer can also detect the ultra-high frequencies at which drones are controlled, so the scanner can easily be used to monitor airports. LETI told socialbites.ca about this.
The device is very suitable for field exploration. You cannot know on which frequencies the people who need to be monitored will be operating, but they will definitely not be missed, thanks to the spectrum analyzer recording all possible signals,” LETI noted.
Every year, communication systems and drone control systems are increasingly moving to higher frequency ranges (ultra-high frequencies – microwave). Modern spectrum analyzers based on digital processors cannot adequately cope with the processing of microwave signals. Using optical processors at the heart of the device can solve this problem.
“Although the spectrum analyzer based on our optical processor is very fast, we identified two main problems that prevent it from covering all the possible frequencies we would ideally like to reach. Therefore, we are now working to resolve these,” said St. Leonid Aronov, senior lecturer at the Department of Theoretical Foundations of Radio Engineering (TOR) of St. Petersburg Electrotechnical University “LETI”, told socialbites.ca.
The problem is that some signals may be distorted or missed during radio monitoring. In addition, old processor algorithms only made it possible to detect signals at certain frequencies, and information was lost between them. Now scientists are looking for ways to solve these problems.
