解釋
軌道波流-
Second, the imaging model built here has taken into account the tilt modulation, the hydrodynamic modulation, and current modulations of radar cross section. consequently, it has realized the imaging simulation of four kinds of wakes with the same imaging model. third, the orbital velocity of ocean wave was considered as the basic dynamic factor, and the imaging model calculates the influence on raw data by the wave m ovement according to the orbital velocity
該模型的主要特點是： （ 1 ）它採用了三尺度復合表面模型的思想來計算海面的電磁散射，考慮了中等尺度波對紋波的進一步調製作用，彌補了傳統雙尺度模型的不足； （ 1 ）它考慮了海浪的傾斜調製作用、流體動力調製作用和流場對雷達截面的調製作用，實現了用統一的模擬模型對四種艦船尾跡特徵進行成像模擬； （ 3 ）它把海面長波的軌道速度作為基本的動態成分，並依此來考慮海面運動對sar回波信號的影響。 -
In this application, the lorentz force generated by the interaction between the current in the wire and the geomagnetic field produces an electro - dynamic drag leading to a fast orbital decay. in this paper, we make an intensive study of the process of de - orbiting using electro - dynamic tether system. the concrete work includes : firstly, i have studied the basic principle of how to generate the electro - dynamic drag, modeled via accuracy geomagnetism, made a concrete analysis of the de - orbiting duration, the magnitude and direction of electro - dynamic drag under the action of the dipole and accurate geomagnetic models, set up a counterbalance between electro - dynamic torque and gravity gradient torque, emulate the de - orbiting process of spacecraft, and compared the change of six orbital factors and the de - orbiting duration under the action of the dipole and accurate geomagnetic models
