设计精确的定位算法是无线传感网络(wireless sensor networks, WSNs)的研究热点。针对距离向量-跳距(distance vector-Hop, DV-Hop)定位算法的定位精度不高问题,提出基于测距修正的差分进化的节点定位算法(RDEL)算法,提高节点定位精度。首先,RDEL算法利用接收信号强度值对跳数值进行修正,然后,通过构建测距误差代价函数,并利用无偏估计对跳距进行校正。最后,通过差分进化算法估计未知节点的位置。仿真结果表明,相比于传统的DV-Hop算法,提出的RDEL算法降

对吉安大修升级后首部SC型双偏振天气雷达,按照升级大纲要求进行性能参数测试,主要性能参数测试表明,动态范围、噪声系数、强度定标、径向速度检验、差分参量等主要参数指标均满足设计要求。接收机水平通道和垂直通道的参数指标经测试两通道之间存有一定偏差,这种不确定偏差会引起双偏振差分反射率ZDR、差分相移ΦDP、差分相移率KDP、相关系数PHV等参量的误差,因此每年汛期前及年终需对雷达系统进行定期巡检标定确保业务使用质量。同时详细给出各性能参数具体测

空气湿度是自动气象站的重要观测要素,其准确度至关重要。为比较DHC2型和DHC1型两种气象用温湿度传感器的湿度测量性能,选取上述两种型号的传感器各100支,以3MS计量检定系统为实验装置,确保比对结果的准确性和代表性,为测量准确度的分析及湿度的修正提供理论参考。结果表明,相较于DHC2型,DHC1型正反行程中正负误差所占比重变化相对平缓,但高湿时正误差率大,更容易出现高湿不退的情况;两种传感器湿度
