Abstract

Microwave emissions due to hypervelocity impacts have been detected by heterodyne receivers in the ground experiments using an accelerator. We aim to establish the detection system of space debris impacts on a space structure via microwave. The emitted powers at several frequencies due to the impact velocity of 10km/sec are estimated from the characteristics at the experimental impact velocity. Considering the emitted power, the receiving antennas and the microwave frequencies, the maximum distances for detecting the microwave emission are 85m at 2GHz-band and 24m at 22GHz-band. The type and location of receiving antennas which can detect the impact on all habitation and experiment modules on the International Space Station are discussed. It is concluded that the impact can be sufficiently detected via a low gain antenna at 2GHz band.
