在3.49-3.51GHZ频段内的典型中国城市环境下，地面信号衰落仍服从经典的指数对数分布。在中度误差（σx =10.291）下，路损指数在3.1-3.7之间。半径2公里的小区内，RMS时延在3-4微秒之间；典型的办公室环境中，存在直达径时RMS时延小于0.1微秒。在城市环境中，多径现象很明显，主要由高层建筑物引起，并以簇的方式存在。在城市中低速移动条件下（接收机移动速度小于100 Km/h）某一强径的生存时间通常超过10分钟，但相对到达时间会发生滑动。单一小区内的传播环境具有一定相关性，如果存

雷达技术是在1987年前后开始应用于储油罐液位测量的。在此之前,它主要用于航海远洋油轮的液位测量,而与用于油罐的测量则有一定差别。从那时起,雷达测量仪器被广泛应用,从测量简单、清洁的产品到粘性产品和污染性产品,如沥青、焦油和未经加工的蜡等。其测量过程是,先建立一个稳固的测量参考点,然后测量雷达波从天线到液面的往返传播时间,从而确定它们之间的确切距离,再根据测量参考点的位置,就能推算出精确的液面位置。 更多还原
