Abstract : To reduce the in-flight bird strike risk, the TNO/FEL laboratory developed the ROBIN system for the RNLAF. The ROBIN system uses singular or summed radar images. Because motion of objects in the radar image provides much information about the nature of the object, motion analysis is an important feature to improve the filtering of radar images. For this reason the project 'Motion Analysis of Bird Migration' was started as a continuation of the ROBIN project. In this report the advantages and disadvantages of different methods of motion analysis are compared. On the basis of experimental results and theoretical aspects, a choice is made for the method of object matching. The principle and implementation of this method is discussed.
