| Popis: | 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. |
