Outline
The microwave radiation intensity measurement on hypervelocity impacts were conducted with the 8 mm microwave radiometer at the hypervelocity impact facility at HAI, CARDC. The paper presented the test results of the microwave radiation resulted from hypervelocity impacts on the semi-infinite aluminum and semi-infinite copper target materials. The projectiles were LY12 aluminum spheres with impact velocity ranged from 1.98 km/s to 4.3 km/s. The projectiles were 5 mm in diameter. The impact angle is 0°. The microwave radiation intensity were measured in the approach of fixing projectiles, varying projectile velocity and target materials. The results showed that the hypervelocity impact induced microwave radiation could be detected obviously under test conditions. The microwave radiation intensity of the semi-infinite copper target materials duo to hypervelocity impacts was higher than that of the semi-infinite aluminum target materials under the same conditions.
