【摘要】 介绍一种采用宽带 PMC 数字接收机作为模数转换和数字下变频设备,以 DSP(TMS320C6416) 作为控制中心,以 SCSI 磁盘作为记录设备的雷达数据采集与记录系统。该系统基于 CompactPCI 工控机平台,数据传输和记录的接口包括 PCI 和 SCSI 等。经过系统测试,数据传输和记录速率达到50MB/s。通过采集与记录某雷达模拟器模拟回波信号,并用 MATLAB 处理程序对记录数据进行分析,证明该采集与记录系统实用可行,满足了某雷达系统的应用需求。更多还原

【Abstract】 A radar data acquisition and recording system based on DSP is presented.It uses a wideband PMC digital receiver board to realize the analog to digital conversion and the digital down conversion.It employs the TMS32C6416 DSP as the control center.And a SCSI interfaced disk is applied as the recording device. The system is implemented on the Compact PCI computer.The data transferring interfaces of the system include PCI and SCSI.The experiments show that the system’s data acquisition and recording speed is up to 50 MB/s.Through tests of the acquisition and recordings of the radar simulator’s simulated echo and the analysis and processing of the recording data in the SCSI interfaced disk by using MATLAB,it shows that the design is typical and practical.And the design meets the requirement of the radar system.更多还原
