With the rapid development of the radar-guided air-to-air missile, its precision strike capability has seriously threatened the survival of fighter aircraft. To address this problem, the jamming model of towed decoy to the radar-guided air-to-air missile is established. The influencing factors of the interference effect of towed bait are studied in this paper. Firstly, the characteristics of the radar-guided air-to-air missile are analyzed, and the missile motion model is established according to the kinematic principle of the missile. Then, combined with the towed decoy jamming technology model and the missile model, the influence of factors such as dry letter ratio and confrontation situation on jamming effectiveness is compared and analyzed. Finally, the usage rules of towed bait in air combat are obtained. The effectiveness of towed decoys against radar-guided air-to-air missiles is verified by simulation experiments, which can provide a reference scheme for pilots to get rid of enemy locks quickly.
In this paper, the problem of large positioning error of infrared coordinated targets for two aircraft formations is studied.
First, based on the combination of spherical coordinates and rectangular coordinates, a mathematical model of infrared
sensor cross-co-location positioning is established. Then, the kernel ridge regression algorithm is used to improve the
singularity of the positioning matrix, and two sets of data with higher precision are selected to calculate the positioning
error covariance matrix. Simulation analysis shows that the algorithm can significantly improve the positioning accuracy
in the entire detection area.
