论文摘要
近年来，在Majes-Arequipa的干旱地区建造了灌溉。随着时间的流逝，灌溉水在较低区域形成潮湿的区域，这可能会带来正面或负面的后果。因此，重要的是要事先知道新灌溉的水从何处出现。实时卫星图像数据的可用性有限仍然是某些应用程序的障碍。 NOAA的环境卫星的数据可用费用和许可证。为了接收数据，用户必须获得必要的设备。在这项工作中，我们提出了一个带有RTL SDR接收器的卫星数据采集系统，两个137-138 MHz设计的天线，轨道子，SDRSHARP，WXTOLMAG和MATLAB软件。我们设计了两个天线，一个旋转门交叉的偶极天线，带有balun和四倍的螺旋螺旋天线。天线参数测量值与通过仿真获得的对应关系非常好。 RTL SDR RTL2832U接收器与我们的天线和软件相结合，形成了用于录制，解码，编辑和显示自动图像传输（APT）信号的系统。结果表明，卫星图像接收是足够的清晰和描述性的，可以进一步分析。
In recent years, irrigations have been built on dry areas in Majes-Arequipa. Over time, the irrigations water forms moist areas in lower areas, which can have positive or negative consequences. Therefore, it is important to know in advance where the water from the new irrigation will appear. The limited availability of real-time satellite image data is still a hindrance to some applications. Data from NOAA's environmental satellites are available fee and license free. In order to receive data, users must obtain necessary equipment. In this work we present a satellite data acquisition system with an RTL SDR receiver, two 137-138 Mhz designed antennas, Orbitron, SDRSharp, WXTolmag and MatLab software. We have designed two antennas, a Turnstile Crossed dipole antenna with Balun and a quadrifilar helicoidal antenna. The antennas parameter measurements show very good correspondence with those obtained by simulation. The RTL SDR RTL2832U receiver, combined with our antennas and software, forms the system for recording, decoding, editing and displaying Automatic Picture Transmission (APT) signals. The results show that the satellite image receptions are sufficiently clear and descriptive for further analysis.
