Radar waveform synthesis for single-mode scattering by a thin cylinder and application for target discrimination

The novel radar waveform synthesis method, for target detection and discrimination, is assessed for the case of thin cylindrical targets illuminated by the radar signal at an oblique angle. The impulse response of an ordinarily oriented wire is approximated analytically, and the aspect-independent, required incident-signal waveforms for the excitation of various single mode return signals are obtained. The method synthesizes an aspect-independent waveform for the incident radar signal which excites an arbitrarily oriented target so that the return signal consists of a single natural resonance mode of the target in the late-time period. When the incident waveform which had been synthesized to excite a particular natural mode for a preselected target is applied to a different target, the return signal will be different from that of the expected natural mode and the target can be sensitivity discriminated.
