Abstract

A method and apparatus for protecting the troops when they exit an armored vehicle is provided by utilizing the universal tail light assembly and providing the assembly with wide field-of-view cameras and other sensors, with screens or displays located within the vehicle to provide situational awareness of the rear of the vehicle, thus to alert troops and their commanders as to external threats prior to troop deployment. In one embodiment, two wide-angle infrared cameras are retrofitted to existing universal tail light assemblies to either side of the vehicle, with the cameras having overlapping fields of view to permit generation of a panoramic view. Moreover, additional sensors such as ultrasonic sensors, LIDARs and laser range finders can be located in the universal tail light assembly, with the subject system not requiring breach of the already-existing armor for the vehicle.

Claims

1. A method for modifying an armored vehicle having armor with existing holes carrying pass-through therein to provide a tail light assembly that when connected provides stealth situational awareness to troops exiting said armored vehicle, comprising the steps of:

modifying as a retrofit package an existing tail light assembly originally provided on an armored vehicle having armor with existing holes carrying pass-throughs therein for electrical connections through the armor, the holes and pass-throughs having locations and sizes designed to preserve armor integrity so as to protect against penetration to the inside of the armored vehicle, said tail light assembly including front and back clamshells with an aperture in the front clamshell and wide angle infrared thermal imaging camera mounted in the aperture for detecting the thermal signature of troops or apparatus in the vicinity of said vehicle;

adding infrared LEDs to the tail light assembly to assist in stealth infrared image detecting, said infrared LEDs being illuminated at all times situational awareness is required;

utilizing existing armored vehicle wiring or routing apparatus and no more than the existing hull pass-throughs that pass wires from the interior of the armored vehicle to the tail light assembly for connecting the wide angle infrared thermal imaging camera to a display within the vehicle such that no new holes or pass-throughs in the armor are added that would otherwise degrade original armor integrity; and

,

displaying within the vehicle images from the wide angle thermal imaging camera for alerting troops within the vehicle as to thermal images of objects or persons in the area surrounding the rear of the vehicle prior to the troops exiting the vehicle at the rear, said existing tail light assemblies being retrofitted with a situational awareness system without sacrificing hull integrity to alert the troops to threats at the rear of the vehicle prior to disembarkation thus to provide situational awareness in low light or no light conditions.

2. The method of claim 1, wherein the camera is a near-infrared camera and the display within the vehicle displays thermal images thus to highlight a human thermal threat at the rear of the vehicle on the display within the vehicle, whereby threats at the rear of the vehicle can be displayed regardless of low light conditions and camouflage.

3. The method of claim 1, and further including the step of replacing incandescent lamps in the tail light assembly with light-emitting diodes.

4. The method of claim 3, wherein the light-emitting diodes operate in the 880-nm region of the electromagnetic spectrum.

5. The method of claim 3, wherein the light-emitting diodes provide illumination at the rear of the vehicle.

6. The method of claim 5, wherein the camera utilized is a standard CCD camera operating in the visible region of the electromagnetic spectrum but having sensors that are capable of detecting radiation in the near-infrared, whereby the additional illumination from the light-emitting diodes permits the use of standard CCD cameras.

7. The method of claim 1, and further including locating sensors within the existing tail light assembly.

8. The method of claim 7, wherein the sensors are taken from the group consisting of acoustic sensors, visible light sensors, LIDARS, radars, laser range finders, thermal sensors, electric field sensors and electromagnetic radiation sensors.
