Bases of dynamic correction of sensitivity coefficients of group of the same sensors (on the example of cosine distribution law)

It is supposed that at an operational phase there is an opportunity to perform measurement of an isotropic background. Carrying out sorting of the measured values in group of the same sensors, in case of similarity of their sensitivity we receive for each sensor a uniform picture of distribution on positions of the sorted list. In case of sensitivity drift of one sensor there is an imbalance: the measured values from this sensor appear in one half more often than in another. Formulas and results of calculations establishing dependence of an imbalance on the size of drift of one sensor as a basis for dynamic correction of coefficients of sensitivity of the same sensors are presented. Similarity of result for the even number of sensors and bigger odd is proved. As an example cosine distribution of the measured random variable is considered. A choice of parameters of this distribution by some criteria of likeness to normal distribution is made.
