The paper performs analysis of remote laser method capabilities to detect pipeline leaks and makes a comparative estimate of different bands to solve a task of remote detection of propane leaks. Shows that in the spectral band of∼13 µm with at least 0.8 % propane content in the leak (approximately twice less than the flammability limit) the task of pipeline leak detection can be solved with correct detection probability close to one and false alarm probability of∼three decimal places with the propane layer thickness on the ground surface being at least 100 cm.
