Controlling pulsed EM scattering of receiving antennas: The one-port case

A time-domain compensation theorem concerning EM scattering of a one-port antenna system is derived with the aid of the reciprocity theorem of the time-convolution type. The theorem describes the impact of a change in the antenna load on receiving-antenna scattering properties. Applications of the theorem are found in controlling the pulsed echo of a receiving antenna as well as in related theoretical aspects of receiving-antenna scattering theory.
