Applying the Reverse Mode of Data Gathering to Improve Panoramic Radio Control

Modern radio monitoring equipment (RME) is able to cover a very wide band of simultaneous analysis (BSA). Nevertheless, the frequency bands to be analyzed, as a rule, significantly exceed it in width. It necessitates the use of a panoramic analysis of the radio environment, which implies the cyclic scanning by RME equipment of a set of adjacent BSAs included in the analyzed frequency range (AFR). At the same time, the unidirectional data gathering mode is considered classic. According to it, firstly, the BSA set scanning in the frequency-increasing direction is completed, and then the RME radio receiver is retuned to the AFR beginning, thus starting a new scanning cycle. However, such a mode is not the only possible one and, in some cases, it turns out to be suboptimal from the standpoint of data gathering efficiency and the probability of detecting signals such as, in particular, single radio pulses (SP). The goal of the work is to increase the efficiency of data gathering and the probability of signal detection by optimizing the RME data gathering mode. The reverse data gathering mode proposed in the work makes it possible to reduce the BSA data gathering interval, and thereby increase the efficiency of data gathering as well as the probability of SP detection. As a result, replacing the classic unidirectional data gathering mode with a reverse mode requires only the adjustment of the software that controls the tuning of RME heterodynes, taking into consideration that the “ARGAMAK-D11” RME model 4 application can increase the efficiency of data gathering by up to 95% and the probability of SP detection by up to 42% in the standard RME operating modes. Thus, the application of a reverse data gathering mode in the panoramic analysis of a radio environment enables the significant improvement of RME performance when detecting signals in wide frequency bands #CSOC1120.
