Amplitude-goniometric passive location of an emitting target in the nonstationary radio channel

Abstract

The further development of the concept related to passive direction finders (DFs) equipped with an energy-measurement channel is implemented. The goniometric-energy method of passive detection and ranging, according to which the slant distance to a target can be determined from its emission in the form of a constant-envelope signal, is generated as applied to the given stationary DFs. In the spatial case, the passive location problem is solved using the time-dependent behavior of the generalized radiolocation coefficient. A complex algorithm is constructed with the aim at jointly estimating the given coefficient and the detection range under the condition that rectilinear uniform motion of an emitting target is simulated on the estimation interval. The computational experiment results are presented to confirm the possibility of practical application of the proposed method.
