9.1 Sensor systems

9.1.1 The sensor system concept

If there is only one sensor for obtaining information on the value of any measured parameter onboard a vehicle, opportunities for determining the accuracy and reliability of this measurement are essentially limited. For example, measurement of noise can be partially suppressed only along with some of the spectral components of the useful signal, and optimal one-dimensional filtration of a signal mixed with noise defines the limit of measurement accuracy. Also, the failure of a single sensor obviously leads to the complete loss of the desired measurement. ...
