Integrated 3D audiovisual threat cueing system

A method of warning an occupant of a host platform of a threat comprising:

• detecting a first threat;
• generating a warning tone responsive to detection of the first threat;
• determining a first estimated location of origin of the first threat relative to the host platform;
• displaying the first estimated location of origin of the first threat on a map, the first estimated location of origin of the first threat being fixed to the map;
• receiving geo-spatial coordinate data from the host platform;
• processing the warning tone based on the geo-spatial coordinate data and the first estimated location of origin of the first threat to produce a directional audio warning signal;
• audibly projecting the directional audio warning signal to provide an audible indication of a direction, relative to the host platform, of the first estimated location of origin of the first threat;
• detecting a second threat;
• determining a second estimated location of origin of the second threat relative to the host platform;
• displaying the second estimated location of origin of the second threat on the map;
• calculating a region of overlap between the first estimated location of origin of the first threat and the second estimated location of origin of the second threat;
• and
• displaying the region of overlap on the map, visually distinguished from the first and second estimated locations of origin of the first and second threats, respectively.

An integrated audiovisual threat warning system comprising:

• a threat detection sub-system configured to detect threats and to determine the estimated location of origin of each threat relative to the threat warning system;
• an audio tone generator configured to generate a warning tone responsive to detection of each threat;
• an audio processor unit configured to receive the warning tone, geo-spatial coordinate data from a host platform with which the threat warning system is associated, and direction information indicating a direction, relative to the host platform, of an estimated location of origin of each threat, and to process the warning tone based on the geo-spatial coordinate data and the direction information to generate a directional audio warning signal;
• a plurality of speakers coupled to the audio processor unit and configured to audibly output the directional audio warning signal including an audible indication of the direction, relative to the host platform, of the estimated location of origin of each threat;
• and
• a control display unit coupled to the threat detection sub-system and configured to receive the estimated locations of origin of the threats and to display the estimated locations of origin of the threats overlaid on a map, the control unit further configured to calculate a region of overlap between an estimated location of origin of a first threat and an estimated location of origin of a subsequent threat, and to display the region of overlap visually distinguishable from the estimated locations of origin of the first and subsequent threats.
