A method providing an estimation of a shooting range with high accuracy by a miss distance estimation and a weapon caliber classification following detection of shooting of firearms with supersonic bullets, and by using novel equations constructed from field shooting data for each caliber in order to ensure a security of a patrol station, a border, troops, a society, a vehicle and a convoy is provided.

Trajectory estimate for a sub-sonic projectile can be derived from sampling a wake contribution of an acoustic signal detected at a multi-detector array. The wake contribution is sampled, in time, and the samples are processed to determine a bearing estimate for the projectile from which the acoustic wake derives.

A radar system, comprising: a receive antenna configured to receive a receive signal reflected from a bullet, the receive signal exhibiting a Doppler shift according to the motion of the bullet; and a detector implementing a set of matched filters each configured to determine a measure of correlation between the Doppler shift of the receive signal and one of a set of pre-stored Doppler shifts, wherein each of the pre-stored Doppler shifts respectively represents the Doppler shift of a bullet passing the antenna at a different speed or a distance of a point of closest approach.

This invention provides impact detection and vehicle cooperation to achieve particular goals and determine particular threat levels. For example, an impact/penetration sensing device may be provided on a soldier's clothing such that when this clothing is impacted/penetrated (e.g., penetrated to a particular extent) a medical unit (e.g., a doctor or medical chopper) may be autonomously, and immediately, provided with the soldiers location (e.g., via a GPS device on the soldier) and status (e.g., right lung may be punctured by small-arms fire).

An automated weapons system is comprised of a human transported weapon for use by a person, a targeting subsystem identifying a chosen target in the area of sighting, an external drone subsystem with a sensing subsystem that communicates to the targeting subsystem, a computational subsystem, positioning means and a firing subsystem. The human transported weapon is for use by a person. It is comprised of a barrel utilized for propelling a fired munitions to aim towards an area of sighting. The targeting subsystem identifies a chosen target in the area of sighting. The external drone subsystem communicates to the targeting subsystem. The external drone subsystem is located remotely to the human transported weapon, and provides communications between the external drone subsystem and the human transported weapon. The computational subsystem, is responsive to the targeting subsystem, for determining where the chosen target is, and then determines where to aim the munitions so that the munitions will strike the chosen target. The positioning means, adjusts the aim of the munitions responsive to the computational subsystem. The firing subsystem fires the munitions at a firing time, at the chosen target, responsive to the positioning means.

Techniques for tracing back a projectile to the projectile origin are described. A method includes detecting projectile track(s) in image(s). Each projectile track crosses multiple pixels in each image. The projectile track(s) correspond to projectile(s). The projectile track(s) in the image(s) are translated to traceback path(s). The traceback path includes a known location and a projectile origin (e.g. the location at which the projectile originated, also termed the shooter's location).

The present invention is a system and device which automatically measures and reports tactical information, allowing the user to efficiently communicate with command units. It is ideally a rifle mounted device, which can measure range, orientation, and position. The present invention can automatically report all tactical information, including enemy combatant positions.
