Abstract

The effects on pulse propagation at millimetre wavelengths of both atmospheric absorption and dispersion are calculated. For subnanosecond pulses, severe broadening of the pulse occurs at frequencies near to atmospheric absorption lines, whilst around the centres of such lines, in regions where the second derivative of the absorption coefficient is negative, pulse compression is found to occur. Furthermore, the frequency at which maximum energy in the pulse is received shifts from the carrier frequency towards regions of lower atmospheric attenuation, while the pulse itself acquires a modulation in the form of a chirp frequency.
