Abstract
A blast initiation detector (BID) was developed for use on Lance and Hera targets to detect the first light from fragmenting warheads. The measured time of first light, in conjunction with the measured time of first fragment impact, provides a method for computing the standoff distance. The standoff distance is a key measure of interceptor performance. A high-speed sled test afforded an opportunity to demonstrate and validate the BID/hit panel standoff measurement for the first time under conditions of known geometry with a moving warhead. The BID/hit panel standoff distance estimate was in agreement with the known geometric standoff distance to within approximately 2%. Lessons teamed from the BID are being used to develop a blast position detector that measures the time and spatial location of the blast.
