| 20100175573 | Explosively formed penetrator detection and passive infrared sensor neutralization system - An apparatus for remote detection or neutralization of an explosively formed penetrator device. A LIDAR or LADAR unit may be used in conjunction with a RADAR unit to both detect the presence of an EFP and neutralize the EFP having an associated passive infrared sensor. The LIDAR unit's wavelength is selected to approximate the signature from the intended EFP target which then causes the safe remote detonation of the EFP. The detected EFP signature may be compared with known signatures and presented to a user via a display terminal. The display terminal may also present associated terrain or GPS data. | 07-15-2010 |
