不同类型传感器的分层融合算法研究

在分布式多传感器数据融合系统中,各单传感器类型不同情况下的融合问题是一类普遍的问题.本文从分层融合算法的推导过程提出了一种解决这一类问题的方法,包括融合状态设定方法、对单传感器滤波结果的状态及其相应方差阵的扩维方法、扩维后的融合与预测方法.同时明确了这种扩维融合算法的实质.

The Study and Experiment on Azimuth Super Resolution Using Phase Information

A method which makes use of the phase information of spectrum of radar echo amplitude signal to make azimuth super resolution is given.Theoretical analyses and simulation results are also given.The results prove that the method is feasible and can effectively resolve whether radar echoes contain a single target or multi targets under the condition that SNR is above 10dB.At the same time,the case in which the time function of antenna mainlobe is not a match for that of echo amplitude is simulated.As a result,the method can efficiently resolve targets under some condition.Finally,the processing results of radar experimental data are presented and indicate again that the method is feasible in practice.
