摘要: 相对于地基ADS-B 系统,星基ADS-B 系统具有覆盖范围广、成本低的优势。但星基ADS-B 信号也存在信号功率低、多普勒频移较大的特点。通过对四天线卫星和目标航迹的仿真计算得出星基ADS-B 信号的功率和多普勒频移,并开发出一套软件系统。该软件可实现对目标发送信号多普勒频移和功率的模拟,实现对卫星覆盖区域、背景地图和目标航迹的显示以及与下位机的数据通信。

关键词: 星基, 功率, 多普勒频移

Abstract: Comparing with ground-based ADS-B, satellite-based ADS-B has the advantages of wider coverage and lower cost but the disadvantages of lower signal power and larger Doppler frequency shift. Through simulation of fourantenna satellite and target trajectory, satellite-based ADS-B signal power and its Doppler frequency shift are calculated. The corresponding software system is developed, which can simulate the Doppler frequency shift and signal power received from target, realizing display of satellite coverage, background map and target trajectory, as well as the digital communication with slave computer.

Key words: satellite-based, power, Doppler frequency shift
