您好!
我尝试根据使用 DCA1000捕获的原始数据开发自己的演示可视化工具。
我已经能够读取运行 OOB 演示的雷达的原始数据。
使用了以下配置:
{ "DCA1000Config": { "dataLoggingMode": "raw", "dataTransferMode": "LVDSCapture", "dataCaptureMode": "ethernetStream", "lvdsMode": 2, "dataFormatMode": 3, "packetDelay_us": 10, "ethernetConfig": { "DCA1000IPAddress": "192.168.33.180", "DCA1000ConfigPort": 4096, "DCA1000DataPort": 4098 }, "ethernetConfigUpdate": { "systemIPAddress": "192.168.33.30", "DCA1000IPAddress": "192.168.33.180", "DCA1000MACAddress": "12.34.56.78.90.12", "DCA1000ConfigPort": 4096, "DCA1000DataPort": 4098 }, "captureConfig": { "fileBasePath": "/home/mettmann/Hochschule/Master/masterarbeit/software/data", "filePrefix": "datacard_record", "maxRecFileSize_MB": 1024, "sequenceNumberEnable": 1, "captureStopMode": "infinite", "bytesToCapture": 1025, "durationToCapture_ms": 1000, "framesToCapture": 5 }, "dataFormatConfig": { "MSBToggle": 0, "reorderEnable": 1, "laneFmtMap": 0, "dataPortConfig": [ { "portIdx": 0, "dataType": "complex" }, { "portIdx": 1, "dataType": "complex" }, { "portIdx": 2, "dataType": "complex" }, { "portIdx": 3, "dataType": "complex" }, { "portIdx": 4, "dataType": "complex" } ] } } }
一个线性调频脉冲的复数原始数据如下所示。 不幸的是、数据的实部和虚部之间似乎存在振幅偏移。
此失调电压来自哪里?
