Description: The paper considers the possibility of the formation of a chaotic signal, which has a higher stealth by using MSKmodulation. Shows a functional diagram of the formation of MSK-modulated chaotic signal. It is shown that the static and dynamic characteristics thus generated chaotic signal with similar characteristics similar observation noise. This theoretically allows for the use of such a chaotic signal to increase the stealth operation of radio communication systems.
