Due to the complexity of the interferometers and high requirement of satellite attitude, a method of passive localization based on Doppler rate-of-change of single satellite channel is presented.

针对单星测向定位中干涉仪设备复杂、卫星姿态测量要求高等不足，提出了一种基于多普勒变化率的单星无源定位方法。

Therefor, a single observer passive location method was proposed by using direction of arrival, phase difference rate-of-change, frequency and Doppler frequency rate-of-change in this paper.

为此，提出一种利用空频域信息的固定单站无源探测定位方法，利用波达方向、相位差变化率、载波频率及多普勒频率变化率实现对运动目标的无源定位。

In addition to the fear of intervention, our short-term rate-of-change measure is giving an oversold reading and the shorter cycles are calling for a recovery during the next two days.

除了害怕干预，我们的短期变化率指标显示出超卖的现象且短期趋势显示将反弹两天。

This paper presents an adaptive scheme that USES both frequency and rate-of-change of frequency measurements to dynamically set ULFS relays if more than one generation outage is experienced.

介绍一种自适应型低频减载装置的方案，它依据频率和频率的变化率，动态的确定减负荷装置的动作情况。

In chapter 2, the basic principle and observability for target location utilizing phase difference rate-of-change and Doppler rate-of-change information of emitter is discussed.

论文第二章介绍了利用相位差变化率和多普勒变化率的定位原理，并且通过系统可观测性分析证明了其与角度信息联合利用跟蹤目标的可行性。
