Patent ID: 8629975

Claim:
A multi-function coherent ladar system having improved spatial resolution and immunity to undesired platform motion and configured to provide an image of a target, the laser radar system comprising: a first transceiver aperture; a second transceiver aperture that is spatially offset from the first transceiver aperture; a signal generator coupled to the first transceiver aperture and configured to generate a multiple sub-code periodic pseudo-noise waveform and to provide the multiple, sub-code periodic pseudo-noise waveform to the first transceiver aperture for transmission therefrom; an orthogonalization device coupled to the signal generator and to the second transceiver aperture, the orthogonalization device configured to provide an orthogonal periodic pseudo-noise waveform to the second transceiver aperture for transmission therefrom and that is orthogonal to the multiple sub-code periodic pseudo-noise waveform; a demodulation device coupled to the first and second transceiver apertures and configured to demodulate reflected periodic pseudo-noise waveforms received from the target by the first and second transceiver apertures; and a signal processing unit coupled to the demodulation device and configured to generate the image of the target from the reflected periodic pseudo-noise waveforms.
