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。

In many signal processing applications the original signals are usually transformed to some other forms which are more appropriate for processing or are otherwise more desirable. Most of them are linear transforms, such as convolution and matched filtering. A transversal filter has the capability of highly parallel operation, as it can perform a large amount of weighted sum operations simultaneously. Therefore, it is especially suitable to perform various linear transforms. Particularly, the transversal filters,...

In many signal processing applications the original signals are usually transformed to some other forms which are more appropriate for processing or are otherwise more desirable. Most of them are linear transforms, such as convolution and matched filtering. A transversal filter has the capability of highly parallel operation, as it can perform a large amount of weighted sum operations simultaneously. Therefore, it is especially suitable to perform various linear transforms. Particularly, the transversal filters, implemented by CCD and SAW devices in sample analog and analog forms, have higher speed of transform, higher packing density and lower power consumption. This paper summarizes the various linear transforms which can be implemented by transversal filters, including chirp-z transform, sliding chirp-z transform, prime transform, discrete cosine transform, discrete cosine prime transform and two dimensional chirp-z transform. This paper also makes some predictions about possible trends in this field in the near future.

在很多信号处理应用中,经常需要将原始信号变换为更便于处理或更期望的形式,这些变换大多为线性变换,例如褶积或匹配滤波等。横向滤波器具有高度并行的运算能力,可以同时完成大量的加权求和运算,因而更适合于完成各种线性变换。特别是由电荷耦合器件和面声器件构成的采样模拟式横向滤波器,更具有较高的变换速度和较低的功耗。本文综述了可采用横向滤波器来实现的各种线性变换,其中包括线性调频z变换、滑动线性调频z变换、素数变换、离散余弦变换、离散余弦素数变换及二维线性调频z变换等,并展望了这方面的发展方向。

In this paper two methods of high-speed decoding of Fire codes for disc error-correction are presented.Method I. For determination of erroneous address, high-speed backward shift circuits are used to perform the cyclic shift of P(x). The maximum number of times of shifting operation for the decoding with a code length N is less than (c + N/C). The erroneous address will directly be given by the counter.Method II. On the basis of Chinese remainder theorem, the erroneous address will directly be given by the counter when P(x) and C are properly chosen. The maximum number of times of decoding shift is less than (e + c).Both methods are suitable for high-speed decoding in the disc storage system where arithmetic operation functions are not available and the zerofilling operation is not necessary. It is also suitable for arbitrary code length.

本文介绍磁盘纠错用法尔码的两种快速译码方法。 方法Ⅰ:在确定错误地址时,P(x)电路的循环移位采用快速反向移位电路,码长为N的最大译码移位操作次数小于(C+N/C)次,错误地址直接由计数器得到。 方法Ⅱ:根据孙子定理并加简化和推广应用,在适当选择P(x)和C后,错误地址直接由计数器得到。最大译码移位次数小于(e+C)次。 两者适用于不具备算术运算功能的磁盘存储器系统的快速译码,不需要补0操作,适用于随机码长。
