A method and system for monitoring at least one of a system, a process and a data source. A method and system have been developed for carrying out surveillance, testing and modification of an ongoing process or other source of data, such as a spectroscopic examination. A signal from the system under surveillance is collected and compared with a reference signal, a frequency domain transformation carried out for the system signal and reference signal, a frequency domain difference function established. The process is then repeated until a full range of data is accumulated over the time domain and a Sequential Probability Ratio Test methodology applied to determine a three-dimensional surface plot characteristic of the operating state of the system under surveillance.

The method of claim 1, wherein the derivation of the at least one state variable of the system from measured variables is accomplished by the cost function, wherein calibrations are utilized which represent a relationship in which measured or sensor values can be determined from at least one state variable. 10. The method of claim 1, wherein the derivation of the at least one state variable of the system from measured variables is accomplished by a filter, with which the sought state variables are estimated. 11. The method of claim 1, wherein the sensor system is a GPS, radar or inertial system for calculation of orientation or position of a vehicle. 12. The method of claim 1, wherein the sensor system is an air data system for an aircraft.
