TL;DR: The singularity expansion method (SEM) for quantifying the transient electromagnetic (EM) scattering from targets illuminated by pulsed EM radiation is reviewed in this paper, where the aspect-independent (extinction) E-pulse and (single-mode) Spulse discriminant waveforms which, when convolved with the late-time pulse response of a matched target, produce null or mono-mode responses, respectively, through naturalmode annihilation.

TL;DR: In this article, an aspect independent radar target discrimination scheme based on the natural frequencies of the target is considered, and an extinction-pulse waveform upon excitation of a particular conducting target results in the elimination of specified natural modal content of the scattered field.

TL;DR: In this article, a new method for radar target discrimination and identification based on the natural frequencies of the target is presented, which consists of synthesizing aspect-independent discriminant signals, called extinction-pulses (E-Pulses) and singlemode extraction signals which, when convolved numerically with the late-time transient response of an expected target, lead to zero or single-mode responses.

TL;DR: In this paper, a spectral-domain integral equation formulation is used to analyze the propagation characteristics of open integrated microstrip transmission lines, and the results obtained are compared to the results of other workers, and good agreement is observed.

TL;DR: In this paper, a frequency domain approach to the E-pulse radar target discrimination scheme is introduced, which is shown to allow easier interpretation of E -pulse convolutions via the Epulse spectrum, and leads to a simplified calculation of pulse basis function amplitudes in the E pulse expansion.
