An Algorithm for Synthesis of Mismatched Filters for Processing of Aperiodic Phase Manipulated Signals

Abstract

The phase manipulated (PM) signals, which autocorrelation functions (ACFs) have small side-lobes, are very important for the radars, sonars, radio-navigation and radio-synchronization systems. The experience, obtained during the past seventy years, shows that the problem of synthesis of aperiodic PM signals, which ACFs have small side-lobes, is extremely hard. A promising approach for solving of this problem is the usage of mismatched filters (MMFs). Accounting this fact in the paper a new algorithm for synthesis of MMFs for processing of aperiodic PM signals is suggested. The results, obtained in the paper, could be applied in the process of development of new radio-communication devices, used for precise measurement of distances.
