For inverse synthetic aperture radar (ISAR) imaging of ships fluctuating with oceanic waves, azimuth echoes of a range cell have to be modeled as cubic phase signals (CPSs) after the range alignment and the phase adjustment. In ISAR imaging based on the CPS model, the chirp rate and the quadratic chirp rate are identified as causes of the target image defocus and need to be estimated with an effective...
Rod-pinch diodes are considered a promising device for flash radiography applications1–3. High brightness x-ray with spot size less than 1 mm can be generated from the rod-pinch diodes if operated at currents more than the critical current.
A fast pulsed power generator using for killing pathogen in blood has been designed and tested. The set can generate a pulse with voltage of 20 kV, pulse width of ∼9.0 ns on a matched load of ∼5 Ω. It was a Blumlein structure and has a single GaAs photoconductive switch. The laser using for trigger the switch was 1.0 mJ and the maximum switch operate current is about 8.0 kA. A dummy solid load which...
A major challenge of Dynamic Binary Translation (DBT) is to efficiently handle the indirect branch. Conventionally, to translate indirect branches (IBs), DBT systems need to conduct address mapping between Source Binary Blocks (SBB) and Translated Binary Blocks (TBB). However, even a dedicated address mapping process still results in non-trivial performance overheads to DBT. This paper first provides...
Heterogeneous multi-core processors have strong potential for performance improvement, energy efficiency and area efficiency, compared to the homogeneous multi-core processors. The present methods of execution migration for heterogeneous multi-core processor suffer in efficiency, cost, compatibility, or programmability. In this paper, we propose a HW/SW code sign migration method based on binary-instrumentation...
A compact ten stage Marx with six parallel 40kV/5600pF capacitors per stage, developed for various pulsed power applications, is described. Every two stages have a common unattached gas switch so there are five switches that of two are trigger switch and three are self-breakdown switch. The spark gaps and capacitors are arranged radially at sixty degree intervals. Unique features of the Compact Marx...
