2.5 误报处理
2.5 False Alarm Processing Methods
1）、上电后，假如存在误报，首先确认周围是否存在标签干扰，如果有的话，
请让其远离天线 2 米以外，避免系统受其干扰。如果没有标签，首先保证命中次数为
8，峰值位置差为 10，其次可依据软件中的报警数据确定各个参数。
1). After power on, if there is false alarms. Firstly, you check whether there is a tag
around. If yes, please put it away from the antenna 2 meters away to avoid the system
from interference. If no, firstly check if the hit count is 8 and
the difference of peak pos max - peak pos min is 10, and then according to the
data in the software to determine every parameters.
2）、假如没有误报，且标签的检测效果不好。首先保证使用的是默认参数，然
后提升检测效果的步骤有一下几种，尽量一次修改一个参数，且数值变化范围不要变
化太大。
2). If there is no false alarm, and the detection is not good. First of all, resume to
factory setting parameters. Then improve the detection step by step. It is better to try
the parameters one by one, the the modification range is not too much. Modify and
test, little by little, to improve the detection.
