Improvement of the accuracy of the reflector distance estimation in the Fresnel zone in the method of the time-domain signal synthesis based on the parametric spectral analysis

Current paper considers the problem of the longitudinal distance estimation on the ra-dar scan data with the help of the parametric spectral analysis methods. It is demonstratedthat the matrix pencil method and the Prony’s method are more capable at recovering thedistance difference between the scanned structures if the time of the calculation is compa-rable to the DFT method. The simulations for the paper are done with the help of themethod of auxiliary sources.
