The article considers an approach to the modification of manipulative impulse sequences based on Barker codes. It is proposed to change the structure of the encoded pulses by the duration of the elementary message, taking into account the change in the duty cycle of their repetition while maintaining the total average energy. Numerical relations are obtained that determine the spectral and temporal parameters for a seven-element pulse sequence, with an increase in the pulse repetition rate by two and three times. Numerical values are calculated that determine the ratio of the duration of the peaks of the cross-correlation functions between the modified and canonical forms of pulse sequences. Reasonable estimates are presented that characterize the increase in the resolution of the peaks of the cross-correlation functions by 4.43 times in the transition to the proposed modified structure of the pulse sequence.
