plosive pressure vessels and projectile delivery packages. FEA provides designers with a tool for simulating the behavior of a design under various loading conditions without expensive prototyping. EMRTC typically uses this type of modeling when designing objects that must survive shock environments such as explosions and gun firings.
EMRTC also has several first-principle hydrodynamic codes, including CTH from Sandia National Laboratories
and uses the Los Alamos National Laboratory based SPH code, SPHINX, and LS DYNA, a finite element hydrodynamic code for structural calculations
Mine Detection Evaluation
The Countermine Test Site was developed to test and evaluate technologies for the detection and destruction of anti-tank and anti personnel mines. The site consists of support facilities and 100 and 200 meter oval flat tracks. Inert or live mines can be located on the tracks. Remotely operated robotic detection/destruction devices can b

EMRTC SODAR /RASS Sounding
The SODAR/RASS system, also simply referred to as the RASS system, a device that measures temperature and wind conditions in the lower at
mosphere up to altitudes of 4 to 5 km. It consists of , International Association of Chiefs of Police
an acoustic based sounding radar, the SODAR, coupled with a Doppler radar, theRASS system. The RASS system senUSses (by means of Bragg reflections) the tra
- jectory and radar signature of a sound pulse emitted by the SODAR as it trave

nto the atmosphere.
The system reveals atmospheric conditions, including temperature inversions and wind spe
ed and direction with altitude. The measurements are accomplished without the need for balloons or other devices to be sent aloft. The specific system components and pricing are detailed later.
The RASS temperature system is based on a
few simple principles of physics: one being the relationsh at New Mexico Tech:
