Sources of Tracking Error in Millimeter Wavelength Missile Guidance Systems

摘要

A number of sources of error degrade the tracking performance of practical millimeter radars. These include receiver noise, target noise, multipath, clutter, servo noise and propagation effects. In this technical note, these error sources are considered, and the available techniques for minimizing their influence are reviewed. A detailed analysis of a typical millimeter radar tracking a military target has been performed in order to evaluate the relative importance of the different sources of tracking error. Both frequency agile and fixed frequency operation are considered. (Author)
