| 摘 要： | 介绍了用于复杂气候条件下采用末敏探测技术识别目标中心的双通道毫米波辐射计的原理和实验分析。在对辐射计归一化天线温度分析的基础上，给出了计算目标回波信号脉宽以及双通道天线扫描目标同一处的时延的方法。高塔实验实测结果表明：双通道辐射计能减小气候等因素对探测精度的影响；在径向，较之单通道辐射计目标中心识别概率有明显提高。

| Abstract: | A dual-channel millimeter-wave radiometer applied in detecting targets accurately under complicated weather condition was proposed. The principle and the structure of the system are given. Based on the analysis of the normalized antenna temperature of the radiometer, the methods of calcu-lating the pulse width of target echo signal and the delay between the different beams scanning the tar?get center were given in detail. High-tower experimental results show that the radiometer can reduce the weather effect on detective precision, and the probability of the target ’ s center identification is higher than that of single-channel radiometer at radial direction. |
