Analysis of Millimicrosecond RF Pulse Transmission

An analysis of millimicrosecond RF pulse transmission through uniform systems is presented. Quadratic approximations for the complex propagation constant are used, and a Gaussian pulse envelope is assumed. Employing Fourier transformation, the received waveforms are obtained for the general case of lossy, dispersive systems. The results are discussed and illustrated separately in terms of pulse distortions due to dispersion, due to losses and due to bandwidth limitations.
