Abstract

Laser micro-Doppler information generated by characteristic motion such as target rotation or vibration is a fingerprintlike feature of a target such as a vehicle/pedestrian. By combining with the Doppler information, it can be used for the classification and accurate identification of traffic participants. Meanwhile, optical sensor based on such technology is easy to integrate with intelligent driving platform or intelligent traffic monitoring and control platform. This paper proposes a laser Doppler and micro-Doppler composite signal simulation scheme based on vehicle vibration characteristics. Laser Doppler and micro-Doppler composite signals in a platform state simulated by a horn and a onedimensional mobile platform, and a reformed smooth pseudo-Wigner-Ville distribution analysis program is prepared for analysis. Based on this, vibration and motion information are extracted, the laser echo signals are constructed effectively, and physical simulation for composite signal of optical sensor are able to perform.
