    • The auto-calibrating Multi-channel Radiometer comprises several antennas (2) sensing the thermal radiation from an object (1). Before the sensed power is getting fed into the n different amplification channels (4.1-4.n), the power might have to be split by a power splitter (3). After the amplification channels, the signal gets recombined by a correlator (5) before getting detected by a square law detector (6) and an integrator (7). An analogue-to- digital converter (8) makes the measurement readable by any personal computer. Additional components are two noise sources (10, 11) connected through cables (13, 14) to a four port dual-directional coupler (15). A high precision temperature sensor (16) connected through a cable (12) to a second channel of the analogue-to-digital converter (8) allows to monitor continuously the physical temperature of the radiometer. The measurement cycle is driven by the personal computer through the digital connections (17, 18).
    • 自动校准多通道辐射计包括几个天线(2),感测来自物体(1)的热辐射。 在感测到的电力进入n个不同的放大通道(4.1-4.n)之前,功率可能必须由功率分配器(3)分压。 在放大通道之后,信号在由平方律检测器(6)和积分器(7)检测到之前由相关器(5)重新组合。 模拟数字转换器(8)使得任何个人计算机都可读取测量值。 附加组件是通过电缆(13,14)连接到四端口双向耦合器(15)的两个噪声源(10,11)。 通过电缆(12)连接到模拟 - 数字转换器(8)的第二通道的高精度温度传感器(16)允许连续监测辐射计的物理温度。 测量周期由个人计算机通过数字连接(17,18)驱动。
