Abstract

Background. The object of the research is digital signal processing systems of moving targets at the background clutter, performing coherent rejection followed by searcher took a recursive filter in which changes in its structure by switching the inverse (recursive) bonds were used to reduce the transient time. The subject of the research is detection characteristics of digital signal processing systems based on recursive RF tunable and fixed structures. The objective of the study is to compare the effectiveness of digital signal processing systems in the transient and steady-state modes with tunable and fixed structures of recursive RF.
Materials and methods. The research of detection characteristics of in transient and steady modes was based on statistical methods of analysis using the method of characteristic functions.
Results. Expressions for the elements of the correlation matrix were obtained on the output of the tunable structure RF in transition mode and on the output of the fixed structure RF in the steady state. The correlationmatrix on the RF output were the starting point of the subsequent analysis of detection characteristics of digital signal processing systems.
Conclusions. The analysis of detection characteristics of digital signal processing systems in the transient and steady-state modes showed that the transients in fixed RF of recursive structure significantly reduce the efficiency of the system and the restructuring of the RF structure avoids the associated losses, approaching theefficiency of the system in steady state.

Key words

transient, signals, processing system, recursive rejector filters, clutter, detection characteristics.
