Choice of parameters of weight functions at spectral processing of signals of microwave level gauges with frequency modulation

The problems of influence of hindrances on an error of distance measurement by a range finder with frequency modulation at signal processing in a spectral area are considered. Considerable influence of a kind of weight function (WF) on result of processing is shown. For an objective choice of kind WF it is offered to add traditional system of WF parameters in a new parameter - a relative error of frequency estimation. The comparative analysis of some traditional WF is carried out.
