This invention resides in a laser radar system for targeting both moving and stationary targets, which is insensitive to alignment errors introduced by mechanical and acoustic perturbations. The laser radar system includes a laser source for projecting a beam of stable, optical, polarized radiation, three separate polarized beam expanders, a think film polarizer, internal optics including a retroreflector, output optics, a 50-50 beam separator, two separate signal detectors for converting electronic signals to analog and a processor for converting analog electronic signals to digital. The optical assembly is configured to compensate for induced misalignment and maintains optimized heterodyne operation in harsh environments.
