Range Laws for Distance Measuring Systems using Frequency Modulation with a Nonlinear Triangular Waveshape

摘要

Range laws are obtained for a distance measuring system which transmits an RF signal. The RF is frequency modulated by a nonlinear triangular waveform, the amount of nonlinearity being specified by a parameter. The nonlinearity may have desirable or undesirable effects; that is, the sidelobe level of the range response may be decreased or increased depending on the shape and amount of nonlinearity. The results of this report may be used to predict range laws of systems which have nonlinear triangular modulation. Alternately, practical nonlinear triangular waveforms may be specified which will reduce the range-law sidelobes. (Author)
