Abstract: |
To study the properties of a new surface-type infrared decoy, the numerical dispersion model and the infrared radiance model of the plates are established. In addition, the temperature of a single plate was measured during combustion experiment, and the spatial position and infrared radiance of each plate are calculated in plate cloud by the two models respectively. Furthermore, the radar images of the plate cloud are simulated and analyzed in dependence of time and direction for single and multiple launching. The result shows that the surface-type infrared decoy can be a point source of interference when the missile is remote tracking. In the meanwhile, the plates cloud shelters the infrared characteristics of the plume and jets of aircraft when the missile is on IR imaging guidance mode. Moreover, With the analysis of the plate cloud dispersion at different intervals and the infrared radiation intensity in the case of different launching number, it can be concluded that a comfortable launching interval can maintain a continuous plate cloud, launching the decoys simultaneously increase the increment of the radiation intensity obviously, the multiple launching is an effective way to enhance the interference property of the decoy. |
