The radar change in speed to distance to an object is time to respects [17]. Measured the distance to stored the one-time memories its plotted with making grease pencil sketch marks on the radar screen. And calculating speed with using skate rules. Advance developed radar systems are the equivalent operation quick and faster using, the computers. Most modern development radar systems are working principles into Doppler radar or radar systems are working principles into Doppler radar or pulse synchronized Doppler radar systems as shown as figure 6.
