A Technique is presented in this paper to isolate one or a few modal free vibrations from a measured free vibration by means of a DFT-bandpass-IDFT procedure. It qreatly improves the situation of the modal parameter identification based on free vibration: The identification accuracy for free vibration modes with small original energy and closely-spaced modes is improved, while the calculating time and computer memory are considerably reduced.

This paper describes a practical technique and method, and its related theoretical problems for receiver calibration of millimeter-wave radiome- ter (of null-balancing Dicke and antenna-channel noise injection type), without commercial noise standards available. An expression is presented, which can be used to calculate the effective output noise temperature of the combination of calibration source and feeding line as temperature dist- ribution of the latter is nonuniform, and its result is discussed. The eff- ects due to the change of reference temperature with operation enviroment are treated too, and a correct formula is given, which is used to estimate measurement values of the antenna radiometric temperature under this con- dition. Although effects of impedance mismatches are not discussed, the calibration curves T_A~X and T_N~Y given in the paper have taken into con- sideration the correction of the effects. The presented basic calibration method and the derived conclusions from the treatments apply to the case of impedance mismatches.

本文研究在无商用噪声标准情况下,毫米波辐射计(零平衡Dicke式天线通道噪声注入型)接收机定标的实用技术、方法及有关理论问题。导出了校准源的馈线温度非均匀分布时,校准源-馈线组合的有效输出噪声温度的计算公式,并对其结果进行了讨论。对参考温度因环境而变化所造成的影响也进行了讨论,并给出此种情况下天线温度测量值的正确推算式。阻抗失配的影响虽未讨论,但所给T_A~X和T_N~Y定标曲线已对此影响进行了修正;所提供的基本校准方法及讨论所得结论都适用于限抗失配情形。
