失锁频率 - Losing lock frequency unlocked frequency
失锁频率 - It is mainly appeared as the electromagnetic wave coupled into less shielded if cable , the if retransmit caused by the coupling between uplink and downlink in an earth station , and the frequency hopping or sweeping interference caused by an unlocked uplink frequency resource
其表现主要有，因中频电缆屏蔽不佳而产生的串扰，因地球站上下行通道存在耦合而出现的中频转发，以及因上行设备频率源失锁而引致的跳频或扫频干扰。 - Considering the fact that the analog system is not so good as the digital system on the respect of variation of bandwidths and on the respect of switch between different bandwidths . this paper proposes to adopt the dds ( direct digital synthesis ) technique that produces chirp signals of different bandwidths to improve the situation of losing tracks for the ocean satellite altitude indicator in measuring coarse surfaces
现在的雷达基本上采用模拟系统产生线性调频信号，由于模拟系统在带宽变化方面和不同带宽间切换方面不如数字系统，本文采用dds （ directdigitalsynthesis ）技术产生不同带宽的线性调频信号以改善海洋卫星高度计在测量粗糙表面时存在的失锁现象。 - In the management of city transportation , navigation of satellite cannot meet the practical requirement because of shielding and interfering of satellite signal . therefore , map matching and dead - reckoning ( dr ) is used to assistant navigation . this combination is defined as gps / dr integrated navigation system , in which the map matching is used for correcting the orientation and distance errors of dr
而在城市交通管理的应用中，由于卫星定位信号经常会受到建筑物的遮挡和干扰，卫星定位无法满足导航的实际要求，通常需用地图匹配和航位推算器( dead - reckoning ， dr )的方法进行辅助导航，这种导航方式称为组合导航系统，其中地图匹配可用来修正dr的方向和距离的系统误差，以便在卫星信号失锁时，提高dr自主定位的精度。
