The accuracy of coordinate measurements in multistatic radar systems with complex consideration for primary measurement errors due to noise, atmospheric fluctuations, and uncertainty in position topo binding

Abstract

By the example of a range-sum three-position active radar system with cooperative reception, a procedure for calculation of the accuracy of measuring the target coordinates that is based on inversion of the multidimensional Fisher information matrix is presented. The set of primary measurement errors in bistatic delays (ranges), which are determined by the action of the noise of the receivers, atmospheric fluctuations of the propagation delay, and uncertainties of the positions topo binding of the multistatic radar system, is taken into account. An example of calculation of the root-mean-square deviations of the errors of the three-coordinate measurement is given.
