    聽力保護器的真耳聽覺衰減的測量方法
  4. The results show that these algorithms for attenuation correction can work well in the valid range and their effects on attenuation correction are almost identical. when attenuation is strong or measurement error of real echo is large, however, the result from the h - b algorithm for attenuation correction is not good

    結果表明：在有效的訂正范圍內，幾種訂正方法均能得到很好的訂正，並且訂正效果幾乎保持一致，但h - b演算法在衰減作用很強或實際回波測量值誤差很大時，其訂正結果就變得不可靠了，從而造成訂正能力下降。
  5. In this paper, firstly, three - dimensional geometrical models of the target and ir flares are established and by using the software vega missile attacking process is real - time simulated visually. secondly, the ir radiation characteristic of the target, background and the ir flares are analyzed, in which the wave radiation of the sun at different time, wind speed, the relative humidity and ir radiation attenuation characteristic of the atmosphere is under consideration. from above the ir image of the target, ir flare and the background are got and then are normalized to gray color image that will be showed in a child window in real time

    本文通過三維建模工具creator建立目標、背景和干擾的三維模型，再通過視景模擬軟體vega生成載機、導彈和目標飛機的可見光場景圖像，實時地對導彈攻擊工程進行可視化模擬；並分析了目標、背景和干擾的紅外輻射特性，計算出傳感器路徑上大氣衰減等等，將經過衰減的目標、背景和干擾的輻射強度量化為灰度圖，以子窗口形式實時顯示；進一步可以使目標和干擾按照各自的運動軌跡運動，便可產生動態的紅外熱圖像序列。
