摘    要:介绍以TransputerT425单片高速并行计算机为中心控制环境,与高速A/D(35MHz,8bit相结合构成的实时高速雷达回波采集系统。该系统的特点是:采集速度高,存贮量大;利用标准的Transputer链路实时完成处理器间的数据传输和通讯;系统采用并行Occam语言编程。这样既充分发挥处理器的并行功能,又使数据采集和数据处理同步进行,这在实时信号采集与处理系统中具有特别重要的意义。

关 键 词:数据采集  数据处理  雷达回波  并行计算机

Abstract:he paper introduces a real-time high-speed acquisition, and storage system of radar video echoes, which uses the high-speed parallel single-chip Transputer T425 as the central CPU and combines it with the high-speed A/D (35MHz, shit), D/A (50MHz, shit)and FIFO. Compared with the present acquisition and storage system of radar video echoes,this system solves the problems for good acquistion result and real time recognition of radar target video echoes. In the meantime, D/A circuit is devised to combine the manual recognition with the automatic recognition so as to enhance the recognition rate of the facility. It is proved practically that the system has the following feattlres: (1) high sampling rate and great storage capacity; (2) fulfiling the data transmission and communication between processors by use of the standard Transputer chains; (3 ) programming with parallel Occam language, so that the system can not only exert the parallel function, hilt also carry out the data acquisition and processing synchronously, which is very important in real-time signal acquisition and processing systems.
Keywords:data acquisition  data processing  real-time  parallel  radar echoes
