A new scheme for Doppler lidar detection by frequency shifted tracking of the reference frequency is described. The main advantages of the scheme are wide tolerable range of the laser instabilities (in principle more than 100 MHz), easy wideband tuning of the tracking frequency, one analog output by A/D converter with a sampling rate of only several times higher then the maximum expected Doppler frequency. It is shown how to account for the chirp history. The use of frequency synthesis for Doppler detection in wide frequency band of laser instabilities is considered.
