description: The object of study is the LORAN-C signal and its modified forms. The purpose of the work is to optimize the control parameters for the formation of the LORAN-C signal to satisfy the spectral mask while satisfying the requirement for the navigation front. As a result of the study, modified LORAN-C waveforms were considered. Their temporal spectral characteristics are obtained for HF filling, and their influence on out-of-band radiation and side harmonics is considered. To obtain the required characteristics of the modified signals, 2 variants of the output circuit were considered: resonant circuits with different quality factors and a third-order bandpass filter. When working on a narrow-band resonant load, additional research is needed to satisfy the temporal parameters of the navigation front. The shape of the navigation front is less affected by the third-order band-pass filter, therefore it is preferable for filtering spurious components.
