Résumé

Microwave interferometry has been applied to study the shock initiation response of TATB-based HE samples in order to perform the simultaneous measurement of the shock and particle velocities. The particle velocity characterization is not possible with the standard phase method. Therefore the new analytic electromagnetic wave propagation method, based on the Doppler frequency shifts of reflecting moving dielectric interfaces, has been developed and applied to the single sustained shock experiment. The experimental results are compared with hydrocode numerical simulations and a good agreement is observed.
