In article questions of calculation of co-ordinates of object in multiposition Doppler RADAR with several sources and one receiver an echo- signals are considered. On the basis of splitting of working space this RSDAR into three-dimensional sectors, the way of direct calculation of co-ordinates of the object, allowing to avoid a problem incompatible system decision of the nonlinear equations is offered. It is shown that sufficient accuracy for practice can be received, using representation of inverse function by a second degree polynom.
