Active repeater jamming suppression via multistatic radar elliptic-hyperbolic location

Abstract

This paper deals with the suppression problem of active repeater range-false-target deception jamming for multistatic radar. In general, the monostatic radar can not distinguish the real signal from echo since the jamming signal shares the same waveform as the real signal. Nevertheless, the multistatic radar can obtain more information about target and jamming based on the multistatic geometry structure. In this paper, we propose an elliptic-hyperbolic location algorithm (EHLA). First, the elliptic and hyperbolic location are combined to obtain the joint location plane where both real and false targets probably exist. Then, exploiting the characteristic that false targets are scattered among the obtained joint plane, the real target locations can be derived based on the shortest distance criteria. At the analysis stage, we evaluate the effectiveness of the proposed method through numerical simulations. The simulation results highlight that the EHLA shares the capability of suppressing the range false target jamming effectively.
