Energy Centrobaric Correction Method Applied in Velocity Accuracy Enhancement in Doppler Laser Radar System
Doppler effect can be used to detect target velocity based on laser radar system. When processing the signal spectrum, error between Doppler frequency and target velocity is caused by picket fence effect. In order to improve the velocity detection accuracy, energy centrobaric correction method is demonstrated to correct discrete spectrum. Experiment data indicate that the velocity accuracy is better than 1 cm/s.
