In order to solve the problem of permanent damage caused by the traditional tensile strength test in insulation ageing assessment of XLPE (extrude low-density polyethylene) cables, this paper presents a new method of aging assessment for XLPE cables insulation based on ultra-low-frequency dielectric response measurements. On the basis of equivalent circuit, the measurement algorithm of dielectric...
Pulse tracking is extensively applied in sampling guidance for intra-pulse analysis, antenna scan analysis, special signal accurate orientation in electronic intelligence (ELINT), as well as in passive radar seeker (PRS). In some real-time application such as PRS system, existed tracking algorithm cannot deal with complex modulated pulse repetition interval (PRI) as wobulated PRI and linear sliding...
To improve the real-time processing performance of MIMO radar signal processing, based on the analysis of working principles of MIMO radar and task level parallelism in multi-core DSP, this paper proposes an approach of MIMO radar algorithm parallel implementation on TMS320C6678. We focus on this high performance eight-core digital signal processor (DSP) and describe how to implement the MIMO radar...
Characterization of SiOx and Al2O3 passivation film and the effect on PERC cells performance were studied in details. Due to >2×1011 cm−2 positive fixed charge in SiOx film, inversion layer is formed on PERC rear side, so that pseudo-FF of cells decreases because of large J02. Additionally, it leads to bad low-light performance because the rear surface recombination velocity (RSRV) increases with...
