Generation of equivalent false target for multiple triplet antenna system

• Modeling of an MTA system EFT generation model • Proposition of a BTGQL algorithm • Obtention of the optimal the amplitude and phase parameters Antenna phase error, as an inherent challenge in a multiple-point source jamming system, severely affects the spatial distribution of equivalent false targets (EFT). To ensure the generation of an EFT position within constraint bounds and measure its positional accuracy, this paper proposes an equivalent false target (EFT) generation method for a multiple-triple antenna (MTA) system. First, through the establishment of spatial geometric relationships between MTA and targets, the distribution law of EFTs is systematically derived. Second, building upon the feasibility analysis of the proposed method, an EFT generation model for MTA system is constructed by defining a constraint range function. Third, a bidirectional time-varying guided Q-learning algorithm featuring a front-back guided strategy is proposed to solve the model, with emphasis on initial optimization and constraint parameter adjustment. Experiment results show that the maximum phase error allowing controllable positions of EFTs (corresponding to the amplitude and phase parameters generated by an MTA system with two triples) is 15°, which represents a 67% improvement compared with a single triple system.
