The study consisted of an introduction, three scans performed for each of the eleven scanners, and an adjacent interview. We utilized a within-subject design. The dependent variables were task completion time and reliability, by which we mean the share of successful scans within a task completion time below 15 seconds. The independent variables were the barcode scanners as listed in Table 1. For each participant the study was recorded on video. We also transcribed comments the participant made during the tasks.

线性调频信号是一种雷达常用的电磁波信号，当雷达信号检测到目标时候，反射后得到雷达回波信号，此时由于多普勒效应，信号的频率发生偏移，这个源码仿真出雷达检测到目标速度信息的回波信号。(LFM signal is a commonly used electromagnetic radar signal, when the radar signal detection to the target time, after reflection of radar echo signal, at this time due to Doppler effect, the signal)
