Popis:	The construction of signals with a low level of side lobes of the impulse autocorrelation function is of great importance in the development of radar systems, and especially of synthetic aperture radars, where a bright point target can overlap a part of the radar image due to insufficiently low sidelobe levels. This paper presents an algorithm for constructing multiphase sequences of long lengths with a low level of side lobes of the impulse autocorrelation function. Using the proposed algorithm for lengths 680, 1024, 2048, 2730, 4096, polyphase pulse sequences were synthesized with the lowest known sidelobe levels.
