Abstract

In this paper, we discuss the possible use of a light-weight lidar system to detect and track a sniper's high-speed bullet. The analysis includes the calculation of the beam waist, the irradiance per pulse, average irradiance, the maximum time between pulses and the minimum pulse repetition frequency, all as functions of range, beam diameter and beam quality (M²). We discuss, briefly, the possible cueing of such a lidar system by an IR system. The measurement of the BRDF of a bullet is briefly described. Finally, we report on the detection range, based on SNR calculations, as a function of energy per pulse, beam diameter and M².
