在过去的几年内,由于技术的发展以及对能在恶劣环境(烟、雾、尘、雨)下工作和做特殊遥测的敏感器需求的增加,毫米波的研制活动在不断扩大。正在研究在各个领域中的应用,但似乎在导弹制导、目标截获和跟踪以及遥感中的应用具有巨大的潜力。现在已经开始进行几项主要测量计划,测量毫米波和亚毫米波的传播效应(衰减、反向散射)、地面和海面散射、多路效应和目标特性的更确切数据。 本文简要地综述了元件、振荡源和接收机的当前技术状态,讨论了上面提到的测量计划。在此基础上,详细讨论了当前的一些重要应用,并对今后应用的前景也做了估计。
In the past few years, the development of millimeter-wave has been steadily expanding due to technological advances and the increasing demand for sensors capable of operating and making special telemetry in harsh environments (smoke, fog, dust, rain). The application in various fields is being studied, but there appears to be great potential for application in missile guidance, target acquisition and tracking, and remote sensing. Several major measurement programs have now begun, measuring more precise data on propagation effects (attenuation, backscatter) for millimeter and submillimeter waves, ground and sea surface scattering, multipath effects and target characteristics. This article gives a brief overview of the state of the art of components, oscillators and receivers, and discusses the measurement plan mentioned above. On this basis, some important applications are discussed in detail, and the future application prospects are also estimated.
