Systems I: Radiometry, Communications, and Radar
To this point we have described detection systems in terms of the (S/N)V or, in the case of heterodyne detection, the (S/N)P. We now apply these performance measures to several practical system problems and in the process we take into account the detailed statistics of the noise and in some cases the signal. In addition, the method of processing the signal after amplification has a significant effect on system performance. We start with radiometry, the measurement of radiation, and use the expected focal plane intensity to determine the output signal while the noise is determined by the detector/amplifier combination. In the case of a simple direct-detection measurement of signal intensity, ...
