摘要
现代城市环境下，林立的高楼引起电渡严重的多径传播，使得通过测向对通信目标进行定位难以奏效。探讨了一种基于场强测量的通信目标定位技术，对定位算法进行了分析推导，分析了定位误差的来源并给出了初步的误差修正方法，实验结果表明了该定位方法在城市环境下的有效性。
In modem city areas, the method for radiate source＇s location based on direction finding doesn＇ t work well because the multitrack propagation caused by the high buildings. A novel method based coverage amphtude measurement to estimate radiate source＇s location is discussed, then the formula of this algorithm are deduced, the causes of error were analyzed and the modifications were given, finally, the experiment proves the availability of this algorithm in city areas.
