无机熔盐中脉冲铝镀层的研究

在190℃的AlCl3-NaCl—KCl共融盐中，对321型不锈钢板进行脉冲镀和直流镀。在钢板上获得银白色铝镀层。X射线衍射结果表明，两种情况均得面心立方结构的铝，但由脉冲镀所得的铝晶粒较小。对镀层进行性能测试分析。发现同为厚10μm的铝镀层，脉冲镀层硬度比由直流镀层高65HV，且脉冲镀层在耐蚀性和与不锈钢基体的的结合力上明显优于直流镀层.

Multi-channel SAR imaging based on distributed compressive sensing

The rapid development of compressive sensing(CS)shows that it is possible to recover a sparse signal from very limited measurements.Synthetic aperture radar(SAR)imaging based on CS can reconstruct the target scene with a reduced number of collected samples by solving an optimization problem.For multi-channel SAR imaging based on CS,each channel requires sufficient samples for separate imaging and the total number of samples could still be large.We propose an imaging algorithm based on distributed compressive sensing(DCS)that reconstructs scenes jointly under multiple channels.Multi-channel SAR imaging based on DCS not only exploits the sparsity of the target scene,but also exploits the correlation among channels.It requires significantly fewer samples than multi-channel SAR imaging based on CS.If multiple channels offer different sampling rates,DCS joint processing can reconstruct target scenes with a much more flexible allocation of the number of measurements offered by each channel than that used in separate CS processing.
