EXPRESS TEST OF THE FREQUENCY HOPPING SIGNAL EXISTENCE IN THE FREQUENCY RANGE ANALYZED BY RADIO MONITORING SYSTEM IN PANORAMIC MODE
During the analysis of radio frequency band occupancy, there is often a situation when the frequency range to be analyzed has a width substantially exceeding the bandwidth of the radio receiving equipment. In such cases, a panoramic mode of data collection and processing is used. The entire frequency range divides into a set of adjacent frequency bands, viewed sequentially one after another. Fast cyclic change-over of the radio monitoring system from frequency to frequency is not a significant obstacle in the detection and analysis of signals that constantly occupy fixed frequency regions, but it can significantly complicate the detection and analysis of signals with a complex frequency-time structure such as frequency hopping signals. This paper proposes and analyzes an algorithm for recognition of frequency hopping signal existence with insignificant computational expenses.
