The paper deals with the problem of the detection and the estimation of parameters of radar signals in the Gaussian white noise from the point of view of the theory of statistical decision. The design principle of the optimum radar receiver for signals of unknown parameters is given according to the characteristics of the high-speed target at distance and to the purposes of radar systems. Unified detection procedures are established the construction and the performances of the optimum radar receivers are obtained.The block diagrams of these results are also shown.Emphasis is given to the case where the prior distributions are unknown, while only two parameters, velocity and distance, are discussed for the case where the prior distributions "re known. For the latter case, the optimum estimations of these two parameters and their properties are derived from the absolute loss criterion.

本文以统计判决理论观点考虑淹没于正态白噪声中雷达信号检测和参数估计问题。根据远距离高速目标的性质及雷达系统的目的,指出未知参数信号最佳雷达接收机的设计原则。建立了统一的检测程序,得出最佳雷达接收机的结构及其性能。也附有这些结果相应的方框图。 着重于论述信号参数先验分布未知的情形,对于先验分布已知的情形,只讨论了目标速度和距离两个参数。在后种情形,以绝对损失标准导出达两个参数的最佳估计程序和它们的性质。

Deviation in localization of a sound source and differential threshold of sound source position were studied on 43 and 60 subjects, respectively. The mean horizontal deviation in sound source localization was found to be 3.1°, and the mean vertical deviation 4.7°. When the two sound sources to be differentiated were situated near the midplane in front of the subject, with the distance between the sound source and the subject kept at 1.15 m, the mean normal differential threshold of sound source position...

Deviation in localization of a sound source and differential threshold of sound source position were studied on 43 and 60 subjects, respectively. The mean horizontal deviation in sound source localization was found to be 3.1°, and the mean vertical deviation 4.7°. When the two sound sources to be differentiated were situated near the midplane in front of the subject, with the distance between the sound source and the subject kept at 1.15 m, the mean normal differential threshold of sound source position was found to be 3.5? As measured in the experiments with binaural presentation of sound, the mean differential threshold of sound source position in terms of binaural intensity difference was 0.70 db, and that in terms of binaural phase difference -28.5 μsec. The horizontal deviation in sound source localization and the differential thresholds obtained with different experimental methods were compared, and their correlation discussed.
