Abstract

1407093 Pulse radar; radio navigation LITCHSTREET CO 24 Aug 1972 [15 Sept 1971] 02891/74 Divided out of 1407091 Heading H4D The disclosure of the Specification is the same as that of Specification 1,407,091, the claims however relate to determining the angles # and # giving the bearing of the other transponder from the own transponder.
