Abstract

An RPG defeat system and method wherein a foam body is placed at a proximate a target. The foam body has a sufficiently low density to be pierceable by an RPG sensor without the RPG sensor being strained sufficiently to create a voltage. The foam body has a compressive strength sufficient to deform the RPG short circuiting a voltage pathway from the sensor to the RPG detonator. The foam body has a sufficient thickness and/or is spaced from the target to deform the RPG short circuiting the voltage pathway from the sensor to the RPG detonator before the sensor strikes the target and is strained creating a voltage.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . An RPG defeat method comprising:
 placing a porous body on or in proximity to a vehicle or structure;   displacing a plug of the porous body allowing an RPG sensor to enter a channel in the porous body without the RPG sensor signaling the RPG detonator; and   the porous body short circuiting an electrical connection between the RPG sensor and detonator before the RPG sensor strikes the vehicle or structure.   
     
     
         2 . The method of  claim 1  in which the porous body is made of foam. 
     
     
         3 . The method of  claim 1  in which the porous body is chosen to have a density and strength sufficiently low to allow the RPG sensor to enter the porous body without the sensor signaling the RPG detonator. 
     
     
         4 . The method of  claim 1  in which the porous body is chosen to have a density and strength range sufficient for the porous body to short circuit the electrical connection between the RPG sensor and detonator before the RPG sensor strikes the vehicle or structure. 
     
     
         5 . The method of  claim 1  in which the porous body is on the vehicle or structure and the method further includes choosing a sufficiently thick body for the porous body to short circuit the electrical connection between the RPG sensor and detonator before the RPG sensor strikes the vehicle or structure. 
     
     
         6 . The method of  claim 1  in which the porous body is spaced from the vehicle or structure and the method further includes choosing a sufficient spacing of the porous body for short circuiting the electrical connection between the RPG sensor and detonator before the RPG sensor strikes the vehicle or structure. 
     
     
         7 . The method of  claim 1  further including encapsulating the porous body. 
     
     
         8 . The method of  claim 1  in which the porous body is mounted in a framework secured to the vehicle or structure. 
     
     
         9 . The method of  claim 1  in which the porous body is unitary in construction. 
     
     
         10 . The method of  claim 1  in which the porous body has regions of different density. 
     
     
         11 . The method of  claim 10  in which a forward region of the porous body has a lower density then a rearward region of the porous body. 
     
     
         12 . The method of  claim 1  further including adding an armor layer between the porous body and the target. 
     
     
         13 . An RPG defeat method comprising:
 placing a porous body on or in proximity to a vehicle or structure;   a plug of the porous body displaced forming a channel allowing an RPG sensor to enter the channel in the body without the sensor signaling the RPG detonator; and   a porous body region proximate the channel deforming the RPG nose cone and short circuiting an electrical connection between the RPG sensor and detonator before the RPG sensor strikes the vehicle or structure.   
     
     
         14 . An RPG defeat system comprising:
 a porous body for placement on or in proximity to a vehicle or structure;   the porous body configured for displacement of a plug of the porous body creating a channel in the porous body allowing an RPG sensor to enter the channel in the porous body without the sensor signaling the RPG detonator; and   the porous body material proximate the channel configured to short circuit the electrical connection between the RPG sensor and detonator before the RPG sensor strikes the vehicle or structure.   
     
     
         15 . The system of  claim 14  in which the porous body is made of foam.
