A combined defense and navigational system on a naval vessel is disclosed. The disclosed system includes a track-while-scan pulse radar which is controlled to provide either navigational information or tracking information on selected targets. Additionally, the disclosed system includes a plurality of guided missiles, each of which may be vertically launched and directed toward intercept of a selected target either by commands from the track-while-scan radar or from an active guidance system in each such missile.

1. In a guided missile wherein an active seeker is used to provide guidance signals during the terminal phase of flight of such missile toward an intercept with a selected target near the surface of the sea, such active seeker including a pulse radar having a gimballed antenna actuable to be pointed

1. In a guided missile wherein an active seeker is used to provide guidance signals during the terminal phase of flight of such missile toward an intercept with a selected target near the surface of the sea, such active seeker including a pulse radar having a gimballed antenna actuable to be pointed at such target, a guidance system comprising: (a) a receiver and decoder, responsive before the terminal phase of flight to command signals from a source outside of the guided missile, for generating guidance command signals for the guided missile toward the selected target on a course to minimize the effect of sea return on signals received by the pulse radar from the environs of such target and for generating pointing signals for the gimballed antenna; (b) means incorporated in the pulse radar for indicating when echo signals are received from the selected target; and, (c) means, responsive to the above-mentioned means, for then disabling the receiver and decoder and deriving guidance command signals and pointing signals from the pulse radar. 2. The guidance system as in claim 1 wherein the receiver in the pulse radar is a monopulse receiver.
