Systems, methods, and computer program products for optically identifying hostile fire strikes to a vehicle. The identification can be that the hostile fire will hit the vehicle, will likely hit the vehicle, hit the vehicle, or likely hit the vehicle. In the case of predictive hits, a warning may be output and the vehicle can take evasive and/or countermeasure actions. In the case of actual or likely strikes to the vehicle, the optical identification can map a travel path of a detected projectile to positions on the vehicle, thus identifying a likely position or area of projectile impact. Such data can be used for inspection and maintenance purposes.

1. A damage assessment system, the system comprising: an infrared (IR) camera mountable on a structure, the system being operative to determine whether the structure was hit or was likely hit by a fired unguided energetic projectile and a position or likely position on the structure where the projectile hit or likely hit, andsaid IR camera having a field of view (FOV) and a predetermined sensitivity sufficient to capture a heat signature of the fired unguided energetic projectile, the heat signature being from small arms fire, and including at least one of a firing component generated upon firing of the projectile, and a friction component generated by friction as the projectile travels through the troposphere, andpixels of said IR camera being operative to capture a portion of a trail of energy associated with the heat signature of the fired projectile;an image processor mountable on the structure and operative to receive signals from said IR camera corresponding to the captured portion of the trail of energy, said image processor being operative to post-process the signals from said IR camera and to make a determination as to whether the fired projectile hit or likely hit the structure and the position or likely position on the structure where the projectile hit or likely hit the structure; andan electronic data storage device to store data regarding projectile hit position or likely hit position on the structure. 2. The system according to claim 1, wherein the structure is a vehicle, the electronic data storage device being accessible when the vehicle is not moving. 3. The system according to claim 1, wherein the structure is a vehicle, the electronic data storage device is accessible by maintenance personnel for post-trip damage assessment and/or by vehicle crew members for during-trip damage assessment. 4. The system according to claim 3, wherein accessing the electronic data storage device includes displaying a diagram of the structure on a display screen and showing indicia on the diagram representative of one or more hit or likely hit positions on the structure. 5. The system according to claim 1, further comprising an alert system operatively coupled to said image processor to generate timely audible, tactile, and/or visible indications that the structure was hit or was likely hit by the fired projectile. 6. The system according to claim 1, wherein the position or likely position on the structure is an estimate zone of impact. 7. The system according to claim 1, wherein the system is configured and operative to capture and process multiple heat signatures from multiple fired projectiles and to determine whether any of the fired projectiles hit or likely hit the structure and the corresponding positions or likely positions on the structure where any of the projectiles hit or likely hit. 8. The system according to claim 7, wherein hit or likely hit data from accessing the electronic data storage device is for providing a map of the structure showing any of one or more hit or likely hit positions of fired projectiles with respect to the structure. 9. The system according to claim 8, wherein the map includes more than one view of the structure and corresponding any of one or more hit or likely hit positions. 10. The system according to claim 1, wherein the stored data regarding projectile hit position or likely hit position on the structure is retrievable via a hand-held maintenance device providing a display operative to display thereon instructions for inspection. 11. A damage assessment system, the system comprising: an infrared (IR) camera mountable on a structure, the system being operative to determine whether the structure was hit or was likely hit by a fired unguided energetic projectile and a position or likely position on the structure where the projectile hit or likely hit, andsaid IR camera having a field of view (FOV) and a predetermined sensitivity sufficient to capture a heat signature of the fired unguided energetic projectile, the heat signature including at least one of a firing component generated upon firing of the projectile, a tracer-related component, and a friction component generated by friction as the projectile travels through the troposphere, andpixels of said IR camera being operative to capture a portion of a trail of energy associated with the heat signature of the fired projectile;an image processor mountable on the structure and operative to receive signals from said IR camera corresponding to the captured portion of the trail of energy, said image processor being operative to post-process the signals from said IR camera and to make a determination as to whether the fired projectile hit or likely hit the structure and the position or likely position on the structure where the projectile hit or likely hit the structure,the image processor generating probabilistic data including a hit probability representing the likelihood that the projectile has hit the structure, andthe probabilistic data indicates that the structure was likely hit when the hit probability exceeds a threshold amount; andan electronic data storage device to store data regarding projectile hit position or likely hit position on the structure. 12. The system according to claim 11, wherein the structure is a vehicle, the electronic data storage device being accessible when the vehicle is not moving. 13. The system according to claim 11, wherein the structure is a vehicle, the electronic data storage device is accessible by maintenance personnel for post-trip damage assessment and/or by vehicle crew members for during-trip damage assessment. 14. The system according to claim 13, wherein accessing the electronic data storage device includes displaying a diagram of the structure on a display screen and showing indicia on the diagram representative of one or more hit or likely hit positions on the structure. 15. The system according to claim 11, further comprising: an alert system operatively coupled to said image processor to generate timely audible, tactile, and/or visible indications that the structure was hit or was likely hit by the fired projectile. 16. The system according to claim 11, wherein the position or likely position on the structure is an estimate zone of impact. 17. The system according to claim 11, wherein the system is configured and operative to capture and process multiple heat signatures from multiple fired projectiles and to determine whether any of the fired projectiles hit or likely hit the structure and the corresponding positions or likely positions on the structure where any of the projectiles hit or likely hit. 18. The system according to claim 17, wherein the probabilistic data is used to provide a map of the structure showing any of one or more hit or likely hit positions of fired projectiles with respect to the structure. 19. The system according to claim 18, wherein the map includes more than one view of the structure and corresponding any of one or more hit or likely hit positions. 20. The system according to claim 11, wherein the stored data regarding projectile hit position or likely hit position on the structure is retrievable via a hand-held maintenance device providing a display operative to display thereon instructions for inspection.
