Explosive Detection System

Systems & Processes Engineering Corporation (SPEC) proposes a man portable explosive hazard detection system composed of 3 subsystems: a miniature class 1 eye-safe LADAR adapted to provide explosive detection and classification through the use of Raman scattering spectroscopy; a 35GHz staring radar with primary and third harmonic cross section measurement capability; and a cell phone detection and jamming set. The group of devices allows detection and classification of explosive residue, detection of metals and metal or electronic assemblies, and the detection and jamming of cell phone triggers. Key to this system is integration into a hand held device which interfaces to a tough book or equivalent computer, allowing it to be carried and operated by dismount troops. The LADAR is an adaptation of the SPEC family of miniature 32 channel scanning LADARs. One channel will receive the transmit wavelength for ranging and 3D imaging, and the other 31 channels are tuned to Stokes backscatter spectral lines of explosives of interest. The fiber DWDM receiver structure allows 0.175nm receive bands with temperature stability of 5% of band over wide 165F to -65F operating band. The LADAR achieves 8/1 signal to noise ratio on single photon detects, allowing near theoretical receiver performance.
