| Abstract(in English) | Coherent laser radars can measure wind velocity from the Doppler velocity of scattered light by aerosols. When spatially large area is to be observed with high time resolution, number of incoherent integration must be decreased, which increases false detections of Doppler velocity. In the present paper, we propose a spatial screening method to decrease number of false detections of Doppler velocity. The performance of the algorithm is confirmed by computer simulations. For example, when signal to noise ratio before FFT processing is 0dB, and number of incoherent integration is 2, probability of accurate detection of conventional method is only 28%. On the other hand, that of proposed method increases to almost 100%. |
