Formulation of the problem. When collecting data for the analysis of the radio environment in wide frequency bands, as a rule, a panoramic mode is used, which implies cyclic scanning of a set of adjacent frequency bands, the width of which is determined by the characteristics of the receiving path of the radio monitoring equipment. At the same time, the unidirectional data collection mode is considered to be classical, in which, completing the scanning of a set of bands in the direction of increasing their frequency, the radio monitoring system (RMS) receiver tunes to the beginning of the analyzed frequency range and repeats the scanning cycle. Since the fraction of RMS work time used directly for data collection is often far from 100%, its maximization is an urgent task. However, the use of unidirectional mode does not always provide the maximum possible fraction of data collection time.

Purpose. Propose a mode of operation of the radio monitoring equipment, which contributes to an increase in the partial fraction of the time of the RMS operation, which falls on data collection.

Results. A reverse mode of data collection by radio monitoring equipment is presented, which does not require hardware costs and can be implemented only by correcting the firmware. Considered is a typical RMS case of using samples with a duration of 640 μs in the analysis of a frequency range of 240 MHz, in which the gain in the fraction of data collection time when using the reverse mode is 20%. It is shown that when operating in bands with a width of several gigahertz, the use of the reverse mode has little effect.

Practical significance. The proposed reverse mode requires only correction of the firmware that controls the local oscillators of the RMS receiver, and provides an increase in the fraction of data collection time by up to 95% in typical RMS operating modes.
