Penetration characteristics of tungsten sphere fragment to typical components of phased array radar

Based on the analysis for the structure of phased array radar, the equivalent models for some vulnerable components of the radar, such as antenna and trunk, were established. The damage mechanism of tungsten sphere fragment to the phased array radar was discussed, the empirical formulas and experimental data for the target equivalent relations and the extreme speed of the fragment were analyzed contrastively, and the penetration characteristics of different tungsten sphere fragment to typical vulnerable components of phased array radar were obtained by calculating. The results show that the anti-damage ability of vulnerability parts of phase-scan radar to tungsten sphere fragment will enhance observably with the augmenting of diameter of tungsten sphere fragment. It provides a technical reference for the design of anti-radiation missile warhead.
