毫米波无源探测的信号仿真和特征研究

Signal Emulation and Character Research of the Passive Detection of Millimeter Wave

摘要: 研究了在一种特定工作模式下,8mm无源探测器探测机场跑道时的输出信号.推导出了辐射计天线波束中心没有建立在坐标轴上情况下的天线温度的计算表达式,利用这一结果对输出信号进行了仿真和信号特征分析.

Abstract: The output for a 8mm passive detector detecting the airport runway in a specific mode is investigated. The expression of the antenna temperature in the case of the beam center offset from the axis is derived. With this expression, it is simulated and analysed for the output in this paper.
