As the wide usage of FPGA( Field Programming Gate Array ) in military and aerospace fields, the reliability of FPGA becomes more and more significant. CLB (Configurable Logic Block) is the main logic unit of FPGA, which can realize combinational logic and sequential logic. Dynamic burn-in test is one of the most important tests in reliability assessment of FPGA, which can make potential defects of...
DC/DC converters are widely used in industrial, aerospace and other fields. The reliability of DC/DC converters is very important for the whole electronic system. Overheat is the key factor infecting the reliability of DC/DC converters because of the power density of the device. Three-dimensional thermal analysis modules include heat distribution analysis and thermal stress analysis at 25 °C in this...
In the process of the traditional method for ISAR imaging, the produced data is extremely huge, so storage and transmission are both big problems. This paper successfully solves the problems by using compressive sensing theory. After the complete motion compensation to the radar echoes, the method of compressive sensing will be used to dispose the range cells before the imaging. It can reduce the...
In sparse representation, a novel algorithm based on local competitions is proposed to improve the performance of FOCUSS. As lp optimized function employed in FOCUSS is a non-convex function, FOCUSS has many local minimum, i.e. FOCUSS often can't get the sparsest solution. To find the sparest representation, a new sparse representation algorithm is proposed, which combines FOCUSS and local competitions...
