摘要
基于截断误差的改进反射波计算算法,运用方法误差理论提高接收端场强精度。由发射点发出的电波分别经过直射与反射路径到达接收点,两者路径的不同会产生附加相移。直射波与地面反射波的合成场强将随反射系数以及路径差的变化而变化,造成合成波衰减现象。接收端信号相位非线性,从而导致信号失真。因此在固定地址通信中,选择站址时,应力求减弱地面反射,或者调整天线的位置和高度,使地面反射离开光滑界面。
Improving algorithm of reflection wave operation based on truncation error uses method error theory to enhance intensity and precision of the receive end. Then, the emission wave reaches the receive end through direct way and reflect way. The difference of two ways may create additional phasic change. The compound field intensity of direct wave and ground reflect wave may change according to the diversity of reflection index and route difference. The compound ware declines. The signal distortion is realized by phase non-linear of receive end signal. When select location, decrease ground reflection, or adjust antenna location and height to avoid ground reflection from slide interface in fixed address location.
