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.

Embodiments include an apparatus comprising a frequency selective electromagnetic receiver and a signal analyzing module. The frequency selective electromagnetic receiver is configured to receive a reradiating electromagnetic signal resulting from a cavity induced modulation phenomenon occurring within cavit(ies). The signal analyzing module is configured to: determine a power spectral density of the reradiating electromagnetic signal. Frequencies are observed at which the amplitude modulation of the power spectral density peaks. A cavity length is determined employing the frequencies of the power spectral density peaks.

A multiband imaging system comprising: an optical module configured for acquiring simultaneously images from a common field-of-view (FOV) scene in a short wavelength spectral band and in a long wavelength spectral band, the optical module comprising a polarizer configured for applying polarization filtering to electromagnetic radiation of the long wavelength spectral band; and a processing module configured to analyze data indicative of received irradiance distribution between the short and long wavelength spectral bands.

Methods and apparatus for locating a weapon by fusing audio and radar data. An exemplary embodiment comprises detecting a weapon firing event with an audio sensor system, detecting a projectile fired from the weapon with a radar system, calculating a state vector associated with the projectile detection, identifying a location of the weapon by backtracking the state vector to the detected time of the weapon firing event time, and communicating the location of the weapon.

A bullet tracking system comprising a sensor sub-system that generates bullet tracking data by tracking a position and range of a bullet discharged from a remote-controlled weapon and traveling to an intended target; a processor that processes the bullet tracking data to determine aim adjustments of the weapon for subsequent firing of bullets to compensate for tracked bullet ballistics to improve an accuracy of the bullets for reaching the intended target; and a control sub-system to make the aim adjustments of the weapon.

A method and respective system are described, suitable for detecting location and/or path of event. The method comprises obtaining input data comprising optical input data from at least one optical sensor arrangement and acoustic input data from an acoustic sensor arrangement. Processing the input data to detect a first signal indicative of selected events in at least one of the optical input data and acoustic input data, and in response to detecting an event registering a time of collection of the first signal and determining an estimated location of the event. Processing input data of other one of the optical and acoustic input data to determine input signal indicative of a second signal associated with the event. Determining time of collection of the second signal and determining a time difference between time of collection of the event. Utilizing the time difference to determine event location.

A device for determining a firing position from which a projectile has been fired at a target object is proposed, comprising: at least one sensor unit for detecting an impact of the projectile in the target object, at least one acoustic sensor unit for detecting a muzzle blast when the projectile is fired, and a determination unit which is arranged to determine the firing position on the basis of the detected muzzle blast and the detected impact.
