In this paper, we present a single-filter Doppler signal discrimination method for an incoherent Doppler lidar system that has been developed by the Korea Atomic Energy Research Institute. For the incoherent Doppler system, we use an injection-seeded pulsed Nd:YAG laser as a transmitter and an iodine filter as a Doppler frequency discriminator. To reduce the temperature-dependence error, a single iodine filter is used to lock the laser frequency and to detect the Doppler frequency shift. The mean squared error of the frequency locking process is 3.87 MHz, which corresponds to a wind velocity detection limit of approximately 1.04 m/s. The range and velocity measurements are performed using a tunable rotating disc. The results are consistent with those of previous studies in terms of the correlation between the signal ratio (signal/reference) and the actual speed of the rotating disc.
