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。

An iron - containing material with an iron grade of over 20 % can be recovered from magnetic separation tailings of liuling iron mine by gravity method. this material can be used instead of partial clayey material to produce portland cement so as to reduce the mine tailings discharge amount to 43. 52 %, to raise the iron recovery from 70. 89 % to 84. 62 % and to reduce the iron ore powder consumption in raw cement mixture and the energy consumption of raw material grinding
