Abstract
Described embodiments provide a laser detection and ranging (LADAR) system. The LADAR system transmits a laser signal including a train of coherent pulses and receives a return signal based on the transmitted laser signal that is reflected from a target. The LADAR system forms one or more range bins of the return signal. Each range bin includes a train of coherent pulses formed based upon the transmitted laser signal. For each range bin, the LADAR system generates a phasogram associated with the train of coherent pulses. The phasogram is generated by determining a relative phase between the return signal and a reference signal. The LADAR system generates a vibration spectrum of the return signal based upon the generated phasogram.
