A dual radio frequency interferometer aided by laser rangefinder and terrain database system utilizes two linear rays of RFI sensors to determine the position of a source of RF energy. The dual RFI system is very attractive in that it is a passive system and cannot be detected by other sensors or systems while it is going through its position determination operation. Furthermore, use of two linear arrays of sensors allows for the elimination of chronic effects inherent in radio frequency interferometers. The two linear arrays can be placed anywhere on a ...
[ We claim:] [1.] A threat detection and weapons targeting system for a vehicle comprising:a first linear array which receives radio signals and is positioned on said vehicle at a known angle relative to a first axis of a reference coordinate system;a second linear array which receives radio signals and is positioned on said vehicle in the same geometric plane as the first array and at an angle relative to the first axis of the reference coordinate system;means connected to said first and second linear arrays to determine first and second planes in which...
