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 this paper, the problem of radar signal detection and parameter estimation submerged in normal white noise is considered in the view of statistical decision theory. According to the nature of long-range high-speed target and the purpose of radar system, the design principle of the best radar receiver with unknown parameter signal is pointed out. Established a unified testing procedures, the best radar receiver structure and performance. Also attached to these results corresponding block diagram. Focusing on the case where the priori distribution of the signal parameters is unknown, only the two parameters of the target velocity and distance are discussed for the case where the prior distribution is known. In the latter case, the best estimation procedure up to two parameters and their properties are derived on the absolute loss criterion.
