Application of sensitivity coefficients for accuracy determination of coordinates calculation by means of radiolocation passive systems

The method of sensitivity coefficients being used as numerically calculated partial derivatives for estimation of absolute values of coordinates inaccuracy with help of range-difference method in systems of passive radar-location is offered. It is shown that sensitivity coefficients are an effective tool for area determination, in which with the set probability a radio emission source can be. In turn, it gives the possibility of construction of radio monitoring expert systems.
