  2. 2 ) radar incidence angle and surface roughness correction : to make radar incidence correction and eliminate the surface roughness effects, a wide range of surface parameters ( soil moisture, surface rms height, correlation length, incidence angle ) was input to the ibm model to simulate the effect of surface roughness and radar incidence angle on the sensitivity of soil moisture to the radar backscattering coefficient. a simple model was established to simulate the effects of incidence angle and surface roughness. 3 ) establishment of soil moisture change inversion model : according to a modified ibm model simulation results, the bare surface backscattering coefficients can be expressed as a funtion of the dielectric component for a given surface roughness when the surface slope greater than 2. 0, which is valid for most nature surface : in above equation, r0 is the surface reflectivity at normal incidence

    本研究中,首先利用基於微波輻射傳輸方程的微波植被模型和積分方程( iem )模型模擬了各種地表土壤水分含量情況下,植被覆蓋、地表粗糙度(包括地表均方根高度和相關長度) 、雷達入射角對c波段(頻率4 . 7ghz )水平極化( hh )雷達後向散射系數的影響,在此基礎上,建立模型消除了植被覆蓋、地表粗糙度、及雷達入射角對雷達後向散射的影響,利用多時相50m解析度radarsatscansar雷達後向散射系數圖像反演得到了地表土壤水分變化模式信息。
  3. Main system parameters " requirements are evaluated and the bistatic sar radar equation is derived. this dissertation also analyzed the range ambiguity caused by ill geometric configuration arrangements for the transmitter and receiver when the airplane platforms fly on the opposite side of the mapping swath, and achieved the requirements to avoid this ambiguity
