摘要
对毫米波被动探测与其他探测体制的性能进行了对比分析,介绍了毫米波被动探测的基本理论,提出了3mm与8mm波段水面金属目标的辐射特性检测方法。设计了用于探测海面金属目标的直接检波式毫米波辐射探测系统,对辐射探测系统的射频前端、天线、信号处理等各个部件展开详细的计算和讨论,构建了一套完整的体积小、重量轻、功耗低,可满足实际探测要求的直接检波式辐射计系统。
Performance of millimeter-wave radiometer passive detection and other detection systems are compared.Basic theory of millimeter-wave radiometer passive detection is introduced,detection method of 3 mm and 8 mm bands radiation characteristics of metal targets on water surface is proposed. A direct demodulation millimeter-wave radiometer detection system for detecting sea-surface targets is designed,RF front-end,antenna and signal processing unit of the detection system are discussed in detail; a direct demodulation radiometer system which features small-size,light weight,and low power consumption is developed.
