Estimation of Accuracy of Algorithm for Measuring Radiofrequency Pulse Parameters

Abstract

This paper discusses the problems and methods of radiofrequency (RF) pulse parameters measurement. The frequency is assumed to be not known. The purpose of this work is to find out how accurately it is possible to measure the parameters of radiofrequency pulse signals. The definitions of main pulse parameters are discussed. The method for estimating time parameters of a pulse (pulse width, pulse rise time and pulse fall time) and the pulse amplitude are described in detail. In addition, the methods of measuring pulse tilt and overshoot are proposed. The description of the simulation procedure is given. The simulations were performed using synthetic test signals with various parameters and signal to noise ratio (SNR). The result of this work is the estimation of the accuracy of radiofrequency pulse parameters (including tilt and overshoot) measurement in the range of SNR from 5 dB to 25 dB.
