The demand on electrical power quality is ever increasing along with the growing technological advancement. Voltage sag is the most frequently happening problem on power system and might cause great economic loss. To solve this problem, Dynamic Voltage Restorer (DVR) is the most efficient and economic device at present. Offers high-quality power is also a(More)
The first important needed to solve problem of voltage quality assessment and interference suppression is accurate detection for three main voltage sag characteristics of amplitude value, duration and phase angle jump. The usual detection methods of voltage sag characteristics including effective value calculation method, peak voltage method and fundamental(More)
Synthetic Aperture Radar (SAR) is an active microwave remote sensor, which could form real-time image around the target. Traditionally, the simulation of SAR imaging algorithm is based on Matlab which is totally software simulation and the final performance is difficult to guarantee. In this paper, the design of the seeker Equivalent Device of Missile-Borne(More)
