THE RADIATION SOURCE DETERMINING DIRECTION ACCURACY RESEARCH UNDER CONDITIONS OF UNCERTAINTY IN THE DIRECTION FINDER ANTENNA SYSTEM ELEMENTS LOCATION
The unmanned aerial vehicle radio source position spatial line parameters determining process model, which allows taking into account both the stochastic nature of phase measurements and the uncertainty in the proper coordinates of the antenna elements of the direction finder has been developed. The dependences of the mathematical expectation of the magnitude of the linear bearing error as a parameter characterizing the accuracy of determining the direction to the radio source from the standard deviations of the distribution of the coordinates of the antenna elements and the measured phase of the electromagnetic wave, assuming their normal nature, are given.
