The satellite launch industry is a multi billion-dollar international industry with over 100 commercial and military satellite launches conducted in 1999 alone. Rocket launches from both Cape Canaveral Air Force Station (CCAFS) and Vandenburg Air Force Base (VAFB) have been observed at operational infrasound stations monitored by the Prototype International Data Center (PIDC). As more IMS infra...

Transient waves, like all other acoustic waves, will diffract around solid objects, such as measurement instrumentation. A derivation of an impulse response function on the surface of a rigid sphere, based on linear, classical scattering theory, is presented. The theoretical impulse response function is validated using an experiment with blast noise. An application of the impulse response funct...
