Abstract
One of the aspects of passive detection and ranging associated with using amplitude (power) measurements in single-position direction finders is discussed. For such a motionless direction finder, a goniometric-energy method of passive detection and ranging is developed, which makes it possible to determine the slant range of the radiating target with partly known parameters of its motion. A solution for a three-dimensional case with due allowance for the nonstationary character of the radio detection and ranging generalized coefficient is obtained. A complex algorithm of comprehensive estimation of this coefficient and the range for the model of straightline uniform motion of the target is constructed. Results of a computational experiment are presented, which confirm the possibility of using the developed method in practice.
