Abstract:

Included in this report are the results of an investigation of scattering matrices of several types of targets. The primary purpose was to investigate the degradation of data resulting from cross section and phase computations by using a scattering matrix whose elements had been degraded by noise. A review of the matrix representation of target scattering characteristics is presented along with a discussion of the measurement system and calibration procedure used to obtain the measured data. The measured data was obtained by using an absolute phase measuring radar system operating at 3 gigahertz. The scattering matrix of three targets, designed to exhibit distinctly different scattering characteristics, was measured at various signal- to-noise ratios. The measured data was then used as input data to an IBM 7090 which calculated cross sections and phase at five polarizations. The calculated data was used to generate degradation curves for each of the three types of targets. In addition, computed vs measured cross section and phase information on each of the three targets is presented for the case of 45-degree linear transmission and reception.
