Reductive group actions on affine quadrics with 1-dimensional quotient: Linearization when a linear model exists
      
Such an action is called linearizable if it is equivalent to the restriction of a linear orthogonal action in the ambient affine space of the quadric.
      
A linear model for a given action is a linear orthogonal action with the same orbit types and equivalent slice representations.
      
We prove that if a reductive group action on an affine quadric with a 1-dimensional quotient has a linear model, then the action is linearizable.
      
We find presentations for the irreducible crystallographic complex reflection groupsW whose linear part is not the complexification of a real reflection group.

At the present paper the available properties of the linear FM signal are summed up. And the transfer function of the compression network analogous to a matched filter is discussed. It is suggested that the program for the active pulse compression system can be accomplished by using a wire-type dispersive ultrasonic delay line. The experimental results of the active system are also given. Following the discussion of the principle for the passive pulse compression system, the practical program of the passive...

At the present paper the available properties of the linear FM signal are summed up. And the transfer function of the compression network analogous to a matched filter is discussed. It is suggested that the program for the active pulse compression system can be accomplished by using a wire-type dispersive ultrasonic delay line. The experimental results of the active system are also given. Following the discussion of the principle for the passive pulse compression system, the practical program of the passive system used in the laboratory is introduced. The experimental results of the passive system are given. The research work on the active pulse compression system with the compression ratio of 100 and the passive one with that of 140 has succeeded. The compressed-pulse width of the former is 5μs, and that of the latter, 3μs. The experimental results, agree with the theoretical estimations.

本文总结了线性调频信号的许多有用特性,讨论了近似于匹配滤波器的压缩网络传递函数。提出了用金属丝色散型超声延迟线完成有源脉冲压缩方案,报道了有源系统的实验结果。在讨论了无源压缩的工作原理之后,报道了实验室采用的无源脉冲压缩的实现方案,给出了无源系统的实验结果。有源压缩100倍和无源压缩140倍的工作系统已经研究成功,前者压缩脉冲宽度为5微秒,后者压缩脉冲宽度为3微秒,实验结果和理论预计非常吻合。

The dynamic range of a digital companded delta codec for transmitting voice signals in a lower bit rate is confined within the limit of linearity between the control level of the pulse amplitude modulator and the signal level. This paper describes a coder using a nonlinear network in which the relationship between the control level of the pulse amplitude modulator and the signal level is approximately linear. It is proved both in theoretical analysis and experiment that the dynamic range of the digital companded...

The dynamic range of a digital companded delta codec for transmitting voice signals in a lower bit rate is confined within the limit of linearity between the control level of the pulse amplitude modulator and the signal level. This paper describes a coder using a nonlinear network in which the relationship between the control level of the pulse amplitude modulator and the signal level is approximately linear. It is proved both in theoretical analysis and experiment that the dynamic range of the digital companded delta codec is improved by using such a coder.

在电话信号低数码率传输时,若使用数字式压伸增量调制器,由于脉冲调幅器控制 电平和信号电平的非线性特性,调制器的动态范围受到一定限制。本文介绍的调制器是 利用非线性网络,使控制电平和信号电平接近线性,因而改善了数字式压伸增量调制器 的动态范围。分析和实验皆证明动态范围的改善是明显的。

The theoretical problems of a compressed-time correlator are investigated from the viewpoint of signal detection. Through discussion of the LMF arid PR signals, some useful conclusions and basic formulas concerning the output signal, spectrum structure, Doppler filter set-up, noise background, SNE gain and signal envelope smoothing are obtained. As a consequence, it has been possible to design an improved sound pulse-compression receiver.

本文从声信号检测的观点出发分析了时间压缩相关器的有关理论问题。结合处理常用的线性调频脉冲信号及拟随机信号的情况,在相关器的输出信号及其频谱结构、多普勒滤波器组的设置、噪声背景及信噪比增益、信号包络的平滑化等方面得到了一些有用的结论和基本计算公式。改进和部分修正了已有的设计理论,为合理地设计近代声信号脉冲压缩接收机提供了依据。
