Abstract
DREV has been involved for the past few years in the development of a new fragmentation characterization method less expensive than those commonly used and providing results that are at least equally significant. The technique is based on the interpretation of the mean velocity spectrum obtained from a Doppler radar used to observe 15 consecutive detonations of a stationary shell. Sampling and retrieval of fragments have always been the most expensive steps in fragmentation testing. Even if these are still present in the new method, a major effort has been made to minimize their costs. In keeping with the radar technique, sampling is limited to the lateral spray of fragments and accomplished with reusable collectors filled with a bulk material. After an experiment is completed, these collectors are carried from the test site to a recuperation facility where the fragments are retrieved from the decelerating material by a magnetic process.
