Synthesis of a Single-Channel Device for Receiving and Primary Signal Processing under Conditions of Structural-Parametric A priori Uncertainty

Abstract

The synthesis of a single-channel broadband device for receiving and primary processing of radio signals that employs the pulse compression technique is presented given the case where its input signals are received in conditions of their structural-parametric a priori uncertainty. The synthesis was carried out based on the mathematical apparatus of the theory of statistical decisions and on the discrete signal representation in the time-frequency domain. The results of prototyping and experimental studies concerning the receiver that was synthesized in accordance with the structural-functional diagram on the basis of spectrum analyzer with pulse compression technique (SAPCT) are briefly presented. An experiment is described that allowed us to verify the possibilities of obtaining the Fourier transform with regard to the elements of input signals, as well as possibilities of detecting and measuring the frequency-time parameters of these signals. These parameters allow us to figure out the structure and characteristics of input signal bursts [6].
