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.

Abstract: A method and system for mitigating the effectiveness of IEDs are disclosed. The method can include detecting IEDs by sensing the presence of a non-linear electronic component of an IED. The presence of a non-linear electronic component of the IED can be detected by illuminating the device with a high power microwave signal containing a plurality of radio frequencies of electromagnetic radiation and receiving sum and/or difference frequency components that are produced by interaction of the illuminating signals with a non-linear IED component and subsequently re-radiated.
