Stand off distance for explosives
Stand off distance for explosives-Standoff techniques have received increasing attention as valuable methods for material analysis at remote distances This is particularly relevant when looking at hazardous contaminants in the environment or residual explosive material, where it is desirable for the analyst to remain at a safe distance from the material being investigatedAt lesser standoff distances, even a small

Detection of explosives, explosive precursors, or other threat agents presents a number of technological challenges for optical sensing methods Certainly detecting trace levels of threat agents against a complex background is chief among these challenges;Ideally, standoff detection occurs at a distance which provides the highest level of safety for the soldier or first responder These shorter wavelength methods have included primarily Raman based methods using visible (532 nm), near UV (355 nm), and deeper UV (262 nm, 248 nm, 224 nm, and 213 nm) excitationTriggers • What existing conditions are changing and are they Better or Worse
Dec 30, 17 · Q Which type of IED is used to deliver an explosive charge to a target with a large standoff distance between the firing point and the target?Mar 06, 12 · Standoff Distances Modifying a site begins with making the most of the existing standoff distance "Standoff distance is key," says David Dickinson, senior vice president with vehicle barrier manufacturer Delta Scientific "Standoff distances provide a clear space where no vehicles are permitted Every inch countsThese distances can be reduced for personnel wearing ballistic protection Note that the pipe bomb, suicide belt or vest, and briefcase or suitcase bomb are assumed to have a fragmentation characteristic that requires greater standoff distances than an equal amount of explosives in

The cavity formed becomes deeper yet when the explosive charge containing the liner is removed some distance away from the plate There is an optimum standoff distance which varies with the liner and charge design Devices of this nature are called lined cavity charges or shaped chargesA shaped charge is an explosive charge shaped to focus the effect of the explosive's energy Different types of shaped charges are used for various purposes such as cutting and forming metal, initiating nuclear weapons, penetrating armor, or perforating wells in the oil and gas industry A typical modern shaped charge, with a metal liner on the charge cavity, can penetrate armor steelWhere Z is the ' scaled distance ' with units of m/kg 1/3, R is the distance (m) from the center of the explosive charge to the target, and W is the weight of the charge (kg);

Abstract We report THz sensing of explosive materials placed up to 30 m away from the emitter The absorption peak of RDX at 0 THz is measured using THz time domain spectroscopy (THzTDS) Experimental results support the possibility of applying THz wave technology for remote sensing and detection of explosives and related compounds at long standoff distancesW is usually the TNTequivalent weight This scaling law indicates that two charges with similar geometry in the same ambient conditions, identical explosive composition, and different size (weight) will produce selfRaman spectra of a sample to detect the presence of explosives in trace quantities, at a standoff distance Partial least squaresDiscriminant analysis (PLSDA) was used to identify peaks in the Raman spectra of the sample, which could better differentiate explosive and nonexplosive
