  This paper focuses on the design and development of measurement technique and processing of signal for the detection of various explosive simulants like RDX(cyclo-trimethylene-tri-nitramine), TNT(Trinitro toluene), Sarin, TATP(Tri acetone triperoxide), their simulants like nitrobenzene, DNT(Dinitro toluene), DMMP(DiMethyl Methyl Phosphonate), acetone, propanol, etc. (in different states of matter) adsorbed on a metallic surface from a standoff distance ranging from few meters up to a distance of 25 meters in the wavelength range of 7-9 μm. The focus also lies on the measurement methodologies and the instrumentation employed in these systems. A dedicated single screen, single user, user friendly Graphical User Interface(GUI) for controlling the entire system, acquisition and processing of the incoming signal and demonstration of results has been developed with the help of Laboratory..
