In the new filter, the angle measurement and the range measurement are sequentially used to estimate the system state, such that a precise linearization reference point is obtained in the range measurement update. 该滤波器分两步序贯处理角度测量和距离测量数据,从而有效地改进了距离测量修正中的线性化参考点。
Real-time data is transmission to increase the rate and shorten the range the target information update cycle time, reliability data that is reliable and true. 实时性要求提高数据传输的速率,缩短各种机动目标信息的更新周期,可靠性即传输数据真实可靠。
Beginning of range in which to exclude scheduled update of offline pages. Measured in minutes from midnight ( zero disables restriction ) 包含安排好的脱机页更新的起始范围。从午夜开始以分钟计时(零表示禁用限制)
A trigger could be used to ensure that an employee's salary is within an allowable range by signaling an error if an update is outside that range. 您可使用触发器确保某个雇员的薪水位于允许的范围内,方法是在更新后的薪水超出该范围外时发出一个错误。
Indicates some factors covering including range, data base capacity, user interface, update cycle and speed of response which should be considered when choosing search engines; 同时指出选择搜索引擎时应考虑的因素,有收录范围、数据库容量、用户界面、更新周期、响应速度等;
