Hyperspectral Classification for Muzzle Flash Recognition from the Silver Fox UAV

One possible approach to discriminate between different projectiles and weapons is to analyze the muzzle flash spectra which is produced when they are fired. While the IR spectrum contains thermal information about the flame the UV portion of the spectrum contains information about the gas chemistry that is usually not affected by reflections - leading to a high signal to noise ratio. The proposed effort extends existing spectral analysis work in the visible and IR to observe the spectra in the UV. An extensive data base of different muzzle flashes and projectiles will be established from which key aspects of the spectra will be determined to enable future rapid assessment of the muzzle flash. Following the initial assessment of a wide range of spectra, a rapid computed tomography imaging spectrometer will be integrated onto the Silver Fox UAV for airborne reconnaissance and assessment of muzzle flashes. The outcome of the proposed effort will be a local airborne surveillance system that can provide rapid assessment of muzzle flashes, thereby discriminating between friend or foe.
