Description
Summary:A technique based on recording radio-wave emission spectra in the microwave region using a scanning wideband receiver is proposed. The obtained spectra are analyzed with a special program using a hardware–software complex. It is shown that the technique allows substances to be distinguished with respect to their qualitative and quantitative composition and changes in their structure to be determined. It is found experimentally that the technique allows a sensitivity of 5–6 Hz/nm to be achieved.
