| Abstract: | The measurement methods of angle changing rate are discussed in single-station passive location.Firstly,the measurement principles of difference,least square curve fitting and kalman filtering are introduced.Secondly,in order to resolve the effect of non-linear filter model,a parallel kalman filtering method with segment is proposed.Lastly,on view of digital filtering,corresponding low-pass filter is designed to process obtained data flow of angle changing rate,which can improve the measurement accuracy of ... |
