  • Abstract
    There are some practical application, where there is a necessity to use pseudo random signal with super small side lobe level (SLL) of correlation function (CF). One region is meteo radars and another one is radars of observing flight field in airport. One of variant of decision the task is to use polyphase Barker codes (PBC), but how it is supposed in the article [1]there is large probability that for large compression ratio (CR) PBC does not exist. In practice there is necessity in compression ratio 100 - 500 and more. The task of receiving polyphase codes for large compression ratio is considered in the report. For solving this task regular method of synthesis of polyphase code was suggested. For CR 81 was found PBC with SLL 1/ 324(-50.2109 dB) for quadruple frequency of discretization [2]. Formally, for large CR polyphase codes that were presented in the article are not Barker codes, but they are very close to Barker codes. For example, for CR 529 is received code with SLL 1.8/N (-48.874 dB) and for CR 1024 - 2.16/N (-53.52dB).
