System, method, and computer program product for indicating hostile fire

摘要

A network for indicating and communicating detection of hostile fire, and systems, methods, and computer program products thereof. Hostile fire is optically detected and identified at a first vehicle and such identification is transmitted from the first vehicle to one or more other vehicles in the network. Data regarding hostile fire directed at the first vehicle can be stored at one or more of the other vehicles and even retransmitted to other vehicles or base stations.

主权项

1. A system for detecting hostile fire, the system comprising:
a first system located at a first position, the first system comprising: an infrared (IR) camera having a field of view (FOV) and a sensitivity sufficient to capture a heat signature of a fired unguided energetic projectile, the heat signature being an image pixel trail representing a portion of a trail of energy of the projectile; an image processor configured to:
receive pixel data from the IR camera, the pixel data corresponding to the captured portion of the trail of energy,calculate, based on the pixel data, a vertical velocity and a vertical acceleration of the pixel data and a horizontal velocity and a horizontal acceleration of the pixel data,calculate an estimated vertical miss distance of the fired projectile based on the vertical velocity and vertical acceleration of the pixel data,calculate an estimated horizontal miss distance of the fired projectile based on the horizontal velocity and horizontal acceleration of the pixel data, andmake a determination as to the likelihood of whether the first position will be hit by the fired projectile by analyzing calculated estimated vertical and horizontal miss distances of the fired projectile.
