基于斜向探测的短波广播覆盖区分析方法

提出了基于斜向探测数据进行短波广播覆盖区分析的一种实用方法。该方法以斜向探测的MUF及其时延数据为基础,利用基于射线理论的反演方法和等比加权的重构方法进行电离层参数分析,最后利用短波传播预测方法实现了短波广播链路的场强预测和覆盖区分析。通过仿真实例验证了方法的可行性,这对短波广播系统的规划设计、性能分析有重要参考意义。

Analyzing Method for Short-wave Broadcasting Coverage Based on Oblique Sounding System

An analyzing method for broadcasting coverage based on oblique sounding system based on oblique sounder is presented,which is featured by following characteristics： first,the critical frequency at the broadcasting circuit midpoint is inversed from the oblique sounding data a based on simple empirical method; second,the critical frequency is reconstructed by geometric proportion weighted method; third,field strength of broadcasting circuit is calculated and the coverage is analyzed. By the simulation and analysis,the practicability of the method is validated. It provides the important basis for design and performance evaluation of short-wave broadcasting system.
