Abstract:

In radar countermeasures, multi-unmanned aerial vehicle (UAV) cooperative trajectory deception plays a significant role in consuming enemy radar resources and masking real targets. However, it is affected by errors in positioning accuracy, UAV positions, and modulation parameters. In regard to this, after constructing a basic model for trajectory deception, this paper focuses on analyzing the impacts of radar priori position errors and UAV position errors on false trajectories. It derives a spatial theoretical model to clarify the relationship between errors and false target deviations, as well as the measurement association conditions. This paper deduces the detection conditions for velocity consistency and the consistency between modulation parameters and radar cross-section (RCS). A comprehensive analysis of spatial coupling errors is conducted, and corresponding compensation schemes are proposed. Simulation experiments demonstrate that the theoretical analysis can effectively estimate the effect of trajectory deception, and the compensation schemes exhibit feasibility and effectiveness.
