Abstract
The present invention provides a laser radar (ladar) imaging system in which both the range of an object being imaged and the velocity of the object can be measured simultaneously and accurately with superior range resolution and with minimal ambiguity. Use is made of a ladar system based on matched-filter cross-correlation of light pulse waveforms that have multiple, simultaneous frequency components with phase variation and incommensurate spectral frequency spacing between frequency components.
