Such properties could be the water content, a possible amount of additionally added water, the content of conducting ions or the percentage of other constituents, having a noticeable influence on the effective complex permittivity versus frequency. The approach is based on measured dielectric data across a significant bandwidth of one or two octaves (or more), and on data analysis using the multi-variate statistical method of Principal Component Analysis (PCA) and Principal Component Regression (PCR). The prototype of a dedicated microwave instrument is described and as an experimental example the viability of the new approach is demonstrated by the exact determination of the percentage of deliberately added water in fruit juices.","PeriodicalId":354225,"journal":{"name":"ICMMT 2000. 2000 2nd International Conference on Microwave and Millimeter Wave Technology Proceedings (Cat.

Significant improvement in dynamic range and clutter rejection are dependent on critical parameters of the ADC devices used by the radar signal processors. The presence of harmonic-related spurious signals in digital signal processors will result in false targets, high false alarm rates and poor clutter rejection in the case of radars and reduction of ECM effectiveness in case of EW systems. Computer simulation indicates that the magnitudes of the spur levels generated by the ADC devices are strictly dependent on input signal bandwidth, sampling rate or clock frequency and number of bits used. Computer simulation further indicates that high resolution and wide input signal bandwidth are not possible simultaneously with non-cryogenic ADC devices.","PeriodicalId":354225,"journal":{"name":"ICMMT 2000. 2000 2nd International Conference on Microwave and Millimeter Wave Technology Proceedings (Cat.

This system features a tree-type fiber link construction to expand the coverage of MSOL-a previously proposed multi-terminal serial optical link scheme. Wavelength division multiplexing (WDM) is newly applied to achieve the tree-type construction, in which multiple numbers of MSOL sub-links (branches) spread from the main link (trunk). The effect of wavelength dispersion upon the expanding capability is analyzed. An experimental system having three sub-links (using 1.3 /spl mu/m, 1.55 /spl mu/m and 1.65 /spl mu/m wavelengths) for a 1.5 GHz band cellular system is constructed to evaluate the fundamental characteristics of the proposed system. As a result, it is shown that the proposed system triples the radio service coverage of The original MSOL with the same signal transmission performance. This system can be used for expanding the service area of cellular portable radios into indoor areas.","PeriodicalId":354225,"journal":{"name":"ICMMT 2000. 2000 2nd International Conference on Microwave and Millimeter Wave Technology Proceedings (Cat.
