Research on Signal Synthesized Method of Loran C Omni-Directional H-Field Antenna Based on Amplitude Superposition
摘要: 本文针对单棒磁天线在接收罗兰C信号时，会因来波方向的不同而产生相位翻转的特性，设计了基于幅度叠加的信号合成算法，并实现了罗兰C信号的合成处理。该算法在FPGA中实现简单，处理过程快速，具有较强的使用价值，已经在所研制的全向磁天线中得到了使用。
Abstract: The single stick H-field antenna induce reversed phase as the waves directions are different in receiving Loran C signal. The signal synthesized algorithm based on amplitude superposition is designed, which actualize the synthesization of Loran C signal. This algorithm which process fast, can easily realized in FPGA, and has been applied in Loran C omni-directional H-field antenna.
