摘要：

Based on minimizing the standard deviation between the echo signal and its model representation, we developed an algorithm for determining parameters of two interfering signals. A numerical simulation was used to assess the validity of the algorithm in the presence of noise. As a result of the simulation, it was possible to reveal the main factors influencing the errors of determining the parameters of interfering signals. The resolving power of the method was estimated. It is shown that the form of the emitted pulse has a substantial influence on the method's resolution.
