摘要:
本文证明了各态历经的随机信号经符号化处理后,得到的极性信号是干稳的,极性相关函数是各态历经的。在此基础上,建立了一般的极性相关函数的数学模型。从而论证了极性相关法的理论依据,拓宽了极性相关法的适用范围。为高精度,低造价、数字化、集成化的专用极性相关仪的研制,提供了一种切实有效的方法。文中还介绍了已研制成功的数字极性相关测速系统的设计方案。
Abstract:
In this paper, it is proved that the polar signal obtained from the symbolization of an ergodic random signal is stationary and that the autocorrelation function of the polar signal is ergodic. Based on these, a general mathematical model for the polar autocorrelation function is set up and the theoretical basis of the polar correlation method is presented. The field of application of the method is thus extended, and a way to develop a high-accuracy, low-cost digital polar correlator consisting of integrated circuits is provided. Finally, the block diagram of a digital system for measuring the average velocity of flow based on the polar correlation principle is given.
