Paper Abstract

Since defense technologies greatly depend on Low Earth Orbit (LEO) military surveillance satellites, anti-satellite (ASAT) operation is the first reaction after a war breaks out. Surveillance satellites with the altitude of <400 km can be small and low cost, which realizes many deployments like drones in the sky. Therefore, ASAT operation targeting such a low-cost satellite by a multi-stage missile is costly. This gives an expectation for a high energy laser (HEL) as an ASAT weapon. However, the use of a ground-based laser (GBL) is limited to use only in clear sky conditions. A space-based laser (SBL) seems to realize an ideal ASAT weapon, but many SBLs are necessary to disable even a few satellites because the SBLs need to go around the Earth. Meanwhile a ballistic-missile defense system using a Chemical Oxygen-Iodine Laser (COIL) carried by a high-altitude airship (HAA) was proposed to intercept a ballistic missile. Since an HAA can always stay in a clear sky, it should also be used for ASAT operations. Only a single system can disable many satellites since it can stay at a fixed location. The beam profile is simulated to estimate the beam intensity at the target satellite. Since the laser beam propagates upward obliquely to the target, altitude-dependent atmospheric turbulence must be considered. The calculation results show that the beam intensity can be high enough to damage the solar panels of the satellite.
