Controllable Synthetic False Target Generation for Multipoint Source Jamming System

Le résumé fourni par la source

In a multi-point source jamming system (MPSJ), the antenna phase error is an intrinsic issue that seriously affects the distribution of synthetic false target (SFT). In order to make the position of SFT locate within the constraint range in the presence of phase error, this paper proposes a controllable SFT generation method for MPSJ systems. First, through establishing the spatial geometric relationship between the triplet antenna and the target, the distribution law of the SFT of the MPSJ system is derived. Second, by introducing the constraint jamming function, the SFT generation model of MPSJ system is constructed. Third, an adaptive golden whale optimization algorithm with adaptive variable inertia weight, golden sine strategy and chaotic map is developed to solve the model. These derive the amplitude and phase parameters, which ensures that the generated SFTs constantly distribute within the constraint range. Simulation experiments show that in the case of 7° phase error, the generated SFTs corresponding to all amplitude and phase parameter is position-controllable. When the radius of the constraint range is reduced to the baseline length of the MPSJ system, the SFT position corresponding to more than 10% of the amplitude and phase parameters is outside the constraint range.
