摘要
针对海上通信时间的确定,基于Longley-Rice建立的模型,我们可以得到电波功率的空间损耗分布,继而求解出电波振动幅值的空间损耗分布。根据信号接收原理,确定同一多跳路径下,船舶可接受信号的范围大小,最终确定能保持联系的时间。
Based on the model established by Longley-Rice, the spatial loss distribution of radio wave power can be obtained, and then the spatial loss distribution of wave vibration amplitude can be solved. According to the principle of signal reception, the range of acceptable signals is determined under the same multi-hop path, and the time to keep in touch is determined.
