接收机动态范围 meaning in Chinese
receiver dynamic range
Examples
- Receiver dynamic range
接收机动态范围 - The rf receiver consists of rf front end and baseband regulation module . the high - intermediate - frequency superheterodyne structure is adopted in the final scheme . the fine sensitivity of the receiver is achieved by two cascaded lna in the front of the system
系统采用超外差式变频结构设计,两级低噪声放大单元级联保证了接收机灵敏度,两级增益控制单元实现了所要求的接收机动态范围,并且整机的线性度也得到了保证。 - The traditional methods of increasing the dynamic range of the receivers , such as sensitivity time control ( stc ) , automatic gain control ( agc ) , and band - pass intermediate frequency ( if ) limiting , are researched . it is pointed out the limitation of the traditional technologies in increasing the dynamic range in wideband digital ew
( 3 )研究了动态范围的相关参数,分析了扩大接收机动态范围的常规方法,如灵敏度时间控制、自动增益控制、中频限幅器和对数放大器等,并分别指出常规方法应用于宽带数字ew接收机的局限性。 - The dissertation tries to eliminate these affection in details : far - near field problem can be relieved by changing the pesudolite ' s signal format and increasing the dynamic range of receivers ; dual - satellite ' s dual directions timing technology and atomic tinier are contributions to enhance synchronization , the constraints of the layout and location of pesudolite stations , such as gdop , proof - interfere etc . , are also focused in
从伪卫星信号格式和接收机动态范围出发改进了远近场问题的影响。研究了伪卫星与卫星精确时间同步。通过对gdop 、卫星间及与用户接收机的共视性、抗干扰性等几个约束条件的分析，对伪卫星基站进行了合理选址和优化布局。
