Measured swept frequency complex scattering data are presented for six 172 scale models of aircraft and one model of a typical pencil or aerospace vehicle-type target with various vertical stabilizer and simple cavity attachments. The measured data span the model frequency bands 2.2 to 4.0 GHz andor 4.0 to 7.6 GHz. The measured data are predominantly for vertical polarization perpendicular to a horizontal plane containing the wings and fuselage of the aircraft at selected sparse aspects. The measurement system, which utilizes somewhat unique background subtraction techniques, has a bistatic angle of either 30 degrees most targets or eight degrees a few pencil-type target orientations. Synthetic pulse response waveforms only pulse envelopes are shown are generated from the measured spectral data. Features of both the spectral and temporal responses are used to extrapolate the potential of substructure target features such as tail stabilizers and cavities in prediction-correlation type identification schemes.
