The millimeter has the largest frequency band and the highest velocity of communication, but it has the highest cost and technical defaults : multi - path effect, reflect and scatter caused by cloud, smoke, water - dropping, the buildings, the grounds and its shape, the interference caus ed by the thunder, the complexity of device, difficult maintenance, and so on. now the band of the leakage coaxial line is up to 3ghz, leakage coaxial line has some advantages : good adaptability to cloud, smoke, water - dropping, the buildings, the grounds and its shapes, good steady field, it has some technical defaults : lower resolution for location and measuring velocity, the more complex of its sending - receiving relay devices, weak anti - interference, the strict demand for the hole size in the line, the cleaner work environment and the higher cost
毫米波具有最大的帶寬和最高的通信速率，但也有最高的成本要求和較難克服的技術問題，即傳播的多徑效應，降水、雲霧、地形、地貌、建築物等的反射散射，打雷時的嚴重干擾，設備復雜，維護困難等等；泄漏同軸電纜的帶寬目前已做到3ghz ，具有對地形地貌建築物的適應性強，場強穩定，但它的定位測速精度低，它的收發中繼設備較復雜，抗干擾能力低，電纜上的開槽有著嚴格的尺寸要求，工作環境要求清潔，成本較高；傳統無線感應技術具有結構簡單，成本低廉，維護方便，定位精度較高的優點，但是，它沒有抗干擾能力。 -
Terrain slope information can be drawn from polarimetric synthetic aperture radar ( sar ) two - dimensional image, so that three - dimensional image can be generated. it differs from two - pass or repeated trace insar that uses interference phase method to obtain topography height. the p - sar three - dimensional image technology uses the stokes matrix formed by two - dimensional images resolution cells, then applying polarimetric synthesize to stokes matrix can produce polarization signature of the scatter cross - section a - (, x ) for any ( ellipticity ) and ( orientation ) polarization state
這種方法不同於重復軌道和雙通道insar系統，不是利用干涉法提取高度信息，而是利用極化sar二維圖像各分辨單元的stokes矩陣，通過極化綜合估計每個分辨單元的共極化散射特性和交叉極化散射特性（極化指紋） ，以及共極化散射特性最大值時對應的極化橢圓度x利極化橢圓方向角，求解地形的高度輪廓。
