Abstract:PN (proportional navigation) law is in wide use. In this paper, the traditional proportional navigation control system is analyzed, then we find that the traditional proportional navigation guidance law is sensitive to the timeto-go (i.e., time to interception) measurement, in other words, the time-to-go estimation error may cause significant degradation in the performance of the PN guidance law. In this paper, we design a new guidance law which is called reduced sensitivity guidance law (RSL) to solve the pro… Show more
