To explore the capability of quad polarimetric SAR images from a new pursuit monostatic mode of TerraSAR-X and TanDEM-X, a novel process chain for ship detection and velocity estimation is proposed in this paper. Compared with the classic processing chain used for single SAR image, more efficient techniques are integrated into this novel chain, which take advantage of the new image mode and its excellent...
Based on VC dimension theory and structural risk minimization principle of statistical learning theory, Support vector machine (SVM) has a prominent advantage in solving classification and fault prediction problems, specifically suitable for small sample, nonlinear and high dimensional pattern recognition problems. However, SVM is originally created for solving binary classification problems. The...
With the shortage of traditional fossil energy and environment problem aggravating, renewable energy and CHP or CCHP, which is considered as a method for the efficient use of energy, have received a great deal of attention. How to improve the utilization rate of renewable energy and achieve maximum economic revenue now seems very important. In this paper, an optimization model of a combined heat and...
To improve the performance of particle swarm optimization and differential evolution, the diploid differential evolution particle swarm optimization was presented according to the genetics rules. The algorithm was applied into the Open Vehicle Routing Problem. In the algorithm, dominant character and recessive character were included in every individual. Particle swarm optimization was implemented...
This paper investigates the allocation of subcarriers and power in the downlink channels of multiuser OFDM systems. The goal is to minimize the total transmit power under the constraints of user data rates and bit error rate (BER). We propose a sub-optimal algorithm to achieve the goal in this paper. We introduce a new factor which is the gain difference between the maximum and the next maximum userspsila...
