摘要：

We propose a model that can simulate the performance of a photonic-integrated FMCW Doppler LiDAR system with various target and system settings. The well-rounded system model can predict the measured target speed and velocity, system axial resolution, beat signal SNR, frequency modulation nonlinearity induced system error, with a new concept for swept-source laser frequency stabilization. Two sets of autonomous driving scenarios are simulated. Simulations confirm that our model yield system performance consistent with the theoretical calculations.
