Scanning ladar with adjustable operational parameters

摘要

A laser radar (LADAR) has adjustable operational parameters to accommodate surveillance of a particular site. The LADAR comprises: a controller operative to adjust operational parameters of said LADAR to accommodate surveillance of said particular site; a laser source governed by said controller to generate a laser beam pulsed at an adjustable pulse repetition rate; an optical scanner; a first set of optics for guiding said pulsed laser beam from said laser source to said optical scanner; a first drive assembly governed by said controller for operating said optical scanner to direct said pulsed laser beam through an adjustable elevation field of regard; a second drive assembly governed by said controller for operating said optical scanner to direct said pulsed laser beam through multiple azimuth fields of regard during said scan of the elevation field of regard, said pulsed laser beam being scanned through each azimuth field of regard at an adjustable single azimuth field of regard scan time; a light detector; a second set of optics for guiding laser echo pulses returned from said azimuth and elevation fields of regard to said light detector which converts said laser echo pulses into electrical echo pulses representative thereof; and a processor coupled to said light detector for receiving said electrical echo pulses and operative to process said electrical echo pulses to generate a range map of the combined azimuth and elevation fields of regard to accommodate surveillance of particular site.
