The article analyzes how different shapes of warheads on missiles affect their visibility to radar. The researchers used high-frequency techniques to calculate the radar cross section of the missile with different warhead shapes. They found that the olive-shaped warhead had a certain radar cross section, which matched measured results. They also calculated the radar cross section for ellipsoid and hemisphere-shaped warheads under different conditions. The study shows that the shape of a missile's warhead can impact how well it can be detected by radar.
