Vdovychenko I. Advancement of retransmitting system for diagnostics of technical objects

Object - a process of parasitic signal spectrum components suppression, a linearization of dependency of informational parameter - radio wave phase incursion, and quasi-definite useful signal enhancement from mixture of signal plus input noise. Purpose - design of methods for transformation and processing of retransmission measurement diagnostic system signals. Methods - simulations of processes for transformation of radio waves and signals, based on fundamental statements of radio engineering. Results - For the first time, analytically and using calculus of approximations were obtained laws of distributions for amplitude, phase and powers of retransmission meter signal in millimeter wave range. Determined parameters of linear function for phase incursion and frequency estimation of a signal which received by diagnostic system with taking into account obtained statistical characteristics. It has been designed a new complex method for analogue-digital processing of input signal of retransmission diagnostic system with super heterodyne type and in which one the accuracy of measurement approaches to potentially achievable. It has been designed a new analogue-digital retransmission diagnostic system of super heterodyne type. Application - UCSDB "Proton" and KhNURE, A.Ya. Usikov Institute of Radiophisycs and Electronics NAS of Ukraine, in educational curses for preparation of masters and specialists of sciences on departments ORT, APVT and RES in KhNURE. Field of application - technical diagnostic systems
