The analysis of the use of chaotic signals filtered through a broadband bandpass filter to ensure stealth and reliability of data transmission operations in radio communication systems is carried out. Time realizations of chaotic signals generated by the well-known Chua and Rikitake generators are obtained. They were filtered using a broadband bandpass filter, and the data obtained was studied using BDS-statistic and crest factor. As a result of the studies, it was found that under certain research conditions, time realizations of Chua generator and Rikitake generator, obtained by broadband filtering, are suitable. Other considered time realizations are not suitable for radio communication systems, since either they have low stealth from the outside observer, or they have an unacceptable crest factor value for radio communication systems. From this we can conclude that filtering chaotic signals using a broadband bandpass filter as a whole is a promising approach to ensure the stealth and reliability of data transmission in radio communication systems. The authors, basing on the conducted research and conclusions from well-known works, consider it appropriate to use broadband filtering to ensure the stealth and reliability of data transmission in radio communication systems when using chaotic signals, along with widely used methods.
