EBSD analysis of the microstructure of al interconnects and their electromigration reliability;

Microstructure and Stress of ULSI Cu Interconnects and Their Impacts on Electromigration;

The sample temperatures were tested in the metallization electromigration experiment.

The algorithm uses the SAR range migration to resolve the PRF ambiguity by searching for a PRF-ambiguity number that minimizes the intensity contrast in the range-Doppler domain.

Chaotic binary code signals were introduced in Synthetic Aperture Radar(SAR),and by taking range migration into account,point target imaging and anti-deception jamming were simulated.

The method can perform range migration correction by using the statistical property of the signal in the range-doppler domain without any information about SAR platform motion,leading to a better accuracy of traditional auto-focusing methods,and further,the PRF-ambiguity can be resolved.

Fast algorithm for airborne SAR range cell migration correction;

Taking point target imaging of airborne side-looking SAR as an example, the range cell migration in the SAR echo signals is analyzed and three types of interpolation algorithms:nearest neighbor approximation,Lagrange interpolation, and sinc function interpolation are studied in this essay.
