In this paper we describe our direct-detection, pulsed, dual-CO2 laser differential-absorption LIDAR (DIAL) system and report the results of measurements using this system to demonstrate the practicability of remote sensing of hydrazine, unsymmetrical dimethyl hydrazine (UDMH) and monomethyl-hydrazine (MMH). The measurements involved LIDAR returns from a topographic target located 2.7 km from the laboratory and, to our knowledge, represent the first test of laser remote sensing of highly toxic hydrocarbon species having broad band as opposed to simple line spectra. It was found during these experiments that atmospheric fluctuations were the major factor limiting the sensitivity of these measurements. Additional experiments were carried out to achieve a better understanding of these fluctuations and of the improvements achievable through signal averaging. The results of these experiments are also discussed.
