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(biāo)距離、目標(biāo)物反射率、光學(xué)效率等參數(shù)代入最大測程推算方程,得出激光高度計最大測程指標(biāo)。
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(jù)月球探測激光高度計實(shí)現(xiàn)200km所需的最小可探測功率,各影響因子與最大測程關(guān)系的分析,確定非合作目標(biāo)可調(diào)衰減法裝置的技術(shù)指標(biāo)。
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(shù)法基礎(chǔ)上,根據(jù)對月測距方程各系數(shù)的影響權(quán)重分析,提出了非合作目標(biāo)可調(diào)衰減法,即:通過對漫反射模擬目標(biāo),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。
