场强预测是分析舰机协同超短波通信距离和通信效果的关键。介绍并分析舰机协同超短波通信视距传播模式,对比分析国际电联ITU-R P.1546建议书和ITU-R P.528建议书给出的场强预测模型,对两种模型的适用性进行研究,提出了一种基于模型综合应用的舰机协同超短波通信场强预测方法。基于该方法,可进一步估算舰机协同超短波通信信干比等关键指标参数,为舰机协同超短波通信可覆盖范围预测提供技术支撑,同时对科学开展舰机协同超短波通信保障提供借鉴。
Prediction of field strength is the key to analyze the communication distance and communication effect of ship-based coordinated short-wave. This paper introduces and analyzes the line-of-sight propagation mode of ship-based coordinated ultrashort-wave communication, compares and analyzes the field strength prediction models given in ITU-R P.1546 and ITU-R P.528, and compares the applicability of the two models Based on the research, a prediction method of the strength of ship-machine coordinated ultra-shortwave communication field based on the model synthesis is proposed. Based on this method, key parameters such as SINR of ship-to-ship cooperative shortwave communication can be further estimated to provide technical support for the coverage prediction of ship-to-ship cooperative shortwave communication, and provide references for scientific cooperation of ship-based coordinated shortwave communication.
