1. A system that is operative during the day and at night to determine whether a position is an intended target of a fired unguided energetic projectile, the system comprising:
- an infrared (IR) camera having a field of view (FOV) and a predetermined sensitivity sufficient to capture a heat signature of the fired unguided energetic projectile, pixels of said IR camera being operative to capture a portion of a trail of energy associated with the heat signature of the fired projectile; and
an image processor operative to receive signals from said IR camera corresponding to the captured portion of the trail of energy, said image processor being operative to process the signals from said IR camera and to make a determination as to whether the position was the intended target of the fired projectile by analyzing a calculated miss distance of the fired projectile.

Abstract
Systems, methods, and computer program products for identifying hostile fire. A characteristic of a fired projectile is detected using an optical system and the projectile'"'"'s travel path in relation to a vehicle is determined. If the determined travel path of the projectile is within a predetermined distance from the vehicle, it is determined that the projectile is hostile towards the vehicle and a warning is output.

12. A method for indicating hostile fire, comprising:
-
electronically detecting infrared radiation of a projectile in a field of view (FOV); electronically calculating a miss distance of the projectile based on electronically stored data for one or more projectile types, the electronically stored projectile type data including, for each type of projectile, projectile velocity data and projectile distance data; and based on said electronically calculating, electronically outputting an indication. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. A method for processing a projectile heat signature, the method comprising:
-
analyzing received electronic data regarding a sensed heat signature of an unguided projectile; and determining a miss distance of the unguided projectile based on the analyzed received electronic data, the miss distance being at least one of a vertical miss distance and a horizontal miss distance. - View Dependent Claims (21, 22, 23, 24)
