Abstract : A device is described which is designed for use in evaluating the performance of pointers in tracking by radar with the Gun Fire Control Systems Mark 57 and Mark 63. The device receives information from the pointing-error channels of the radar, and after modifying this information, utilizes it to provide a measure of tracking accuracy through the use of timing clocks. The limitations of other methods of evaluating this kind of tracking, such as by optical checksighting or by use of the kymograph, are discussed in the appendix. (Author)
