It has been revealed, that useful properties of codes with low mean sidelobe level of autocorrelation function are manifested when the impulses pack is jointly processed in the form of low relative level sidelobes of cumulative autocorrelation function. The use of codes with low mean sidelobe level potentially allows to provide the lowest sidelobe level of cumulative autocorrelation function in case of non-coherent accumulation, as well as to ensure a low sidelobe level in case of coherent accumulation. Criteria of search of codes with low mean sidelobe level lasting from 10 to 26 elements by method of exhaustive search, way of the formation of packs from them the probing impulses, the reached sidelobes levels of cumulative autocorrelation function and comparison with M-sequences at a non-coherent and coherent ways of accumulation are given in work.
