Processing of Signals and Analysis of Errors in Measurements of Electromagnetic Parameters of Radar-Absorbing Materials in the Time Domain

Аннотация

A mathematical model describing the processing of measurement information in the course of determining the reflection and transmission factors of radar-absorbing materials by means of sounding with the use of ultra-short electromagnetic pulses is proposed. The use of the method of kernel smoothing to eliminate the influence of the noise of the measurement equipment as well as a Fourier window transform for the purpose of realizing a transition to the frequency domain is evaluated. Estimation of the random and systematic measurements is carried out.
