摘要： A first method includes receiving a first reflected radar signal from a target in a first field of view and receiving a second reflected radar signal from a target in a second field of view offset from the first field of view by a predetermined distance; transforming the first and second reflected radar signals to obtain first and second sets of frequency coefficients, from which a frequency-dependent phase difference is obtained; and calculating a time-delay from the slope of the frequency dependence. A second method includes obtaining summed difference values between the first and second radar responses, where each of the summed difference values corresponds to different time shifts between the first and second radar response, and deriving from the summed difference values a time-delay associated with the target's motion from the first field of view to the second field of view. A third method combines the time-delays or associated speeds obtained from independent estimators.

摘要翻译：第一种方法包括：在第一视野中从目标接收第一反射雷达信号，并且在第二视野中从目标接收来自目标的第二反射雷达信号，偏离第一视野预定距离; 转换第一和第二反射雷达信号以获得第一和第二组频率系数，从中获得频率相关的相位差; 以及从频率依赖性的斜率计算时间延迟。第二种方法包括获得第一和第二雷达响应之间的相加差值，其中每个相加的差值对应于第一和第二雷达响应之间的不同时间偏移，并从相加的差值得出与目标的动作从第一视野到第二视野。
