According to the parameters such as minimum detectable power , range and reflectivity of simulant target , meteorological visibility and optical efficiency , the maximum range of laser altimeter was figured out by the range - finding equation 將最小可探測功率、模擬目標距離、目標物反射率、光學效率等參數代入最大測程推算方程,得出激光高度計最大測程指標。
According to the minimum detectable power required by the spaceborne laser altimeter for 200km maximum range and the analysis result of the effect between the maximum range and the equation ' s each parameter , the specifications for noncooperative regulable attenuation setting were fixed on 根據月球探測激光高度計實現200km所需的最小可探測功率,各影響因子與最大測程關系的分析,確定非合作目標可調衰減法裝置的技術指標。
Based on the analysis of the effect on the maximum range of the equation ' s each parameter and the traditional method of extinction ratio , the noncooperative regulable attenuation - measure the minimum detectable power of laser altimeter on the condition of constant miss probability by attenuating the laser power transmitting to the diffuse reflected simulant target - was put forward 在傳統(tǒng)的消光系數法基礎上,根據對月測距方程各系數的影響權重分析,提出了非合作目標可調衰減法,即:通過對漫反射模擬目標,衰減出射激光功率,在一定的漏警概率條件下測量激光高度計的最小可探測功率。
