根据遥感技术原理，对卫星遥感与四波段野外辐射计（EXOTECH－100美国）在麦蚜 灾 害监测中的使用情况进行了研究比较。结果表明，四波段野外辐射计具有很好的适用性。并 在此基础上,通过对四波段野外辐射计EXOTECH－100进行改造，自制了病虫害监测仪，在麦 蚜灾害遥感监测中成功使用，提高监测效率和测量的准确率。卫星遥感由于成本高、可用数 据有限，不便于在麦蚜灾害监测中应用。
According to the principle of remote sensing technology, the use of satellite remote sensing and four-band field radiometer (EXOTECH-100 USA) in the monitoring of wheat aphid disaster were studied and compared. The results show that the four-band field radiometer has good applicability. Based on this, the four-band outdoor radiometer EXOTECH-100 was modified to produce a pest and disease monitor, which was successfully used in remote sensing monitoring of wheat aphid disasters to improve monitoring efficiency and accuracy of measurement. Due to the high cost and the limited data available, satellite remote sensing is not suitable for the monitoring of wheat aphid disasters.
