选用打印机做为雷达的终端记录设备,是因为它记录的数据可供长期保存,设备简单,尤其是被记录的数据具有立即直观可读的特点。打印机的误码率和纸带穿孔机为同一数量级,而且打印机工作时是把主机送出的数据代码直接印在纸上,不用经过任何其他设备转换,所以打印的数据是可信的。红外激光雷达在跟踪飞行物体时,以每秒20次的采样频率连续不断地将测出的距离值、角度值、角修正量值、以及各种标记符号共102个二进制的信息,输至数据终端记录设备。用 The use of a printer as a terminal recording device for radar is because the data it records can be stored for a long time and the equipment is simple. In particular, recorded data has immediate, intuitive and readable characteristics. Printer error rate and tape punch machine for the same order of magnitude, and the printer is working to send the host data code printed directly on the paper, without any conversion by other equipment, so print the data is credible. Infrared laser radar tracking objects in the flight, the sampling rate of 20 times per second continuously measured value of the distance, the angle value, the amount of angle correction, and a variety of symbols and a total of 102 binary information input to the data Terminal recording equipment. use
