An effective sparse array extension method for maximizing the number of consecutive lags in the fourth-order difference co-array is proposed, leading to a novel enhanced sparse array structure based on co-prime arrays (CPAs) with significantly increased number of degrees of freedom (DOFs). One method to exploit the increased DOFs based on nonstationary signals is also proposed, with simulation results...
As the distributed energy is environmental and renewable, micro-grid (MG) has attracted widespread concern since it is raised, and it is becoming the future direction of the power system. In order to connect MG to the grid and make it available to loads, the power quality must meet the requirements set. In that case, energy storage and filtering is two main ways to achieve the goal effectively. This...
In order to meet the needs of recognizing the targets under the moving space background by micro spacecraft target detector (MTD). According to the particular characters of the spatial background, this paper proposes an algorithm which combines the image centroid registration with the single difference method, named the Centroid Registration Difference Algorithm. In this algorithm, we labeled only...
