Abstract:
A method for detecting degradation of an electromagnetic radiating tube system comprising the steps of:collecting sensor data values X from a plurality of n sensors disposed to sense operating characteristics of an operating electromagnetic radiating tube system; entering said sensor data values X into the function F=F(x1, x2, . . . , xi)=&Sum;k=1n&it;â€ƒ&it;&Sum;j=1n&it;â€ƒ&it;&Sum;k=0âˆž&it;â€ƒ&it;&Sum;l=0âˆž&it;â€ƒ&it;cijkl&it;xik&it;xjlwhere Cijkl are calculation coefficients, and Xik, Xjl correspond to each of an n number of sensor parameters and F corresponds to a value indicative of degradation of said operating electromagnetic radiating tube system.
