Dynamic range and linearity trade-off in detectors for interferometric radiometers - Electronics Letters

چکیده
The dynamic range and error performance of the diode power detector used to denormalise the digital correlations in interferometric radiometers is analysed by means of a second-order model of the diode response. This gives an easy method to establish system dynamic range as a trade-off between both the error contribution of measurement uncertainty and diode nonlinearity. The method is illustrated by analysing the power measurement system of the MIRAS-SMOS instrument.

Modeling the Trade-off between Manufacturing Cell Design and Supply Chain Design
Nowadays, we are witnessing the growth of firms that distribute the production capacity of their products to a wide geographic range to supply the demand of several markets. In this article, the relationships and interactions between cell design and supply chain design are investigated. For this purpose, a novel integrated model is presented for designing dynamic cellular manufacturing systems ...
متن کاملIntercomparison of monochromatic source facilities for the determination of the relative spectral response of erythemal broadband filter radiometers.
The relative spectral responses of erythemally weighted broadband radiometers determined at three different laboratories are compared, and the systems are described. The results of measurements of four different broadband radiometers are discussed. Although the common dynamic range of the measured relative spectral responses is approximately 10(4), the differences in the relative spectral respo...

For comparison, the error rate variations of uncoded FSK with LDI detection when BT, = 1 have also been plotted in Figs. 2 4. It is mentioned here that the parameters F,,, and F,, in a Gaussian channe...

Design of Global Positioning System (GPS) receiver with a low noise amplifier (LNA) in the front end remains a major design requirement for the success of modern day navigation and communication system. Any LNA is expected to meet the requirements like its ability to add the least amount of noise while providing sufficient gain, perfect input and output matching, and high linearity. However, mo...
