HAPREX Planning

Abstract

HAPREX is an ABMDA-sponsored project dealing with studies of the effects of high altitude striated ionization on radar performance. This project employs barium clouds, released at high altitudes, which are ionized by solar radiation and striated by gradient drift forces produced by winds and (E vector) x (B vector) forces. The use of barium was originally sponsored by ARPA under Project SECEDE. ABMDA continued this sponsorship to assist in the development of assessment and mitigation techniques to optimize BMD radar system performance in a nuclear environment.
