Abstract
LADAR systems and methods are disclosed. LADAR systems include a LADAR transmitter configured to emit a laser signal from a platform and a LADAR receiver configured to detect the laser signal returning from a target moving relative to the platform. The LADAR receiver includes a dynamic receiver filter with a receiver bandwidth (which may be about equal to the linewidth of the laser signal) and a tunable receiver center wavelength. The LADAR receiver is configured to adjust the receiver center wavelength to a wavelength that is Doppler-shifted due to the target velocity. Methods include transmitting a laser signal from a platform, returning the laser signal from a moving target, adjusting a dynamic receiver filter to a receiver center wavelength that is based upon the center wavelength of the returned laser signal (that includes a Doppler offset due to the relative velocity of the target), and receiving the returned laser signal.
