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 the radio signals are received, the first and second planes comprising respective coordinates from the first axis and from a second axis and an angle of arrival of the radio signals; and

    means to convert the first and second planes to a directional vector relative to the vehicle, taking into account the orientation of the first and second linear arrays relative to the reference coordinate system and the orientation of the vehicle relative to the reference coordinate system.
