本文着重介绍本处理系统在微型机上对遥测数字信号进行处理的理论依据,过程和结果。本文先后叙述了遥测数字信号处理的过程和技术以及利用快速傅里叶变换(FFT)进行功率谱估计和快速相关分析等处理中的若干技巧问题。由于该系统是用汇编语言构成的,而且方法上采用了一些特殊处理,因此具有精度高,速度快,经济效益好等优点。同样,本系统也可用作雷达、地震、遥感、光学、电学等数字信号的处理系统。 This article focuses on the theoretical basis, process and results of the processing system for processing telemetry digital signals on a microcomputer. This paper describes the process and techniques of telemetry digital signal processing and several techniques in the processing of power spectrum estimation and fast correlation analysis using Fast Fourier Transform (FFT). As the system is composed of assembly language, and the method used some special treatment, it has the advantages of high precision, high speed, good economic returns. Similarly, the system can also be used as a radar, seismic, remote sensing, optical, electrical and other digital signal processing system.
