description: The subject of the graduate qualification work is shape changed envelopes of radio pulses of limited duration that meet the requirements of the RNS "LORAN-C" and four-stage radio pulses with shape changed envelopes formed by the key method of formation. The given work is devoted to search for shape changed envelopes of signals, that meet the requirements of the RNS LORANâC, minimize their out-of-band emissions to ensure the transmission of additional information together with the navigation signal, and the implementation of a control device based on the key method of formation. Three proposed forms of the envelope of a finite-duration radio pulse and their effect on spectral characteristics are investigated. The influence of the number of generator cells used on the spectral and temporal characteristics is investigated, the minimum number of GC is calculated to meet the requirements of the system. The effect of transients on the side emissions of a four-stage signal with a selected envelope shape is investigated. A control device has been developed to generate a four-stage signal of the required shape. The terminological features of the subject area are considered, specialized mathematical software MATLAB and Micro-Cap are applied.
