Statement of the problem. To consider(examine) possibility of definition of spatial co-ordinates of a source of a radio emission on the basis of the analysis of degradation of a spectrum of the signal, called by mutual moving of a radio intake and a radiation source.

Purpose. Investigation of the possibility of passive spatial coordinate measurement based on joint processing of the Doppler frequency measurements of the radiation source and the trajectory function of the movement of the radio receiver.

Results. On the basis of the analysis of the analytical parities characterising speed of mutual moving of a source of radiation and a radio intake which defines change of frequency position of spectral components of a signal, the computing algorithm has been generated, allowing to carry out calculation of coordinates of a source of radiation. The developed computing algorithm which basis is the iterative system of the nonlinear equations, is based on a method of the tangents, providing comprehensible accuracy of decisions at enough fast convergence. On the basis of the received decisions the computing experiment, allowed to estimate influence of such factors as speed of movement of the carrier of a radio intake, digitization time has been made at formation trajectory readout and readout of Dopler frequency, degree of high-rise instability of a trajectory on accuracy of definition of spatial coordinates of a source of radiation.

Practical significance. The results presented in job in the form of computing structures, and also the received dependences of a linear error of a fixing as functions from various parameters, allow to formulate requirements to realisation of a way spatial estimation of coordinates, based on Dopler effect.
