AbstractA novel, adaptive waveform coherent LADAR concept is proposed to provide a robust Automatic Target Recognition (ATR) sensor with the capability to meet Air Force objectives. The compact, rugged solid-state LADAR operates at eyesafe wavelengths and is capable of stand-off detection ranges to 20 km or more. Simultaneous precision range, Doppler and micro-Doppler target signatures are extracted with an efficient signal processing architecture. Range resolution of one foot and simultaneous velocity precision better than 1mm/sec is anticipated. It is argued that unprecedented low probability of misidentification and low probability of false alarm rates will be obtained through absolute scale measurements coupled to vibration signatures. Target characteristics can be optimally probed by the base waveform and its ability to overcome camouflage and clutter that can defeat passive, RF and mm-wave sensors. The Phae U program constructs a 1st order, physics-based coherent ladar signature simulator to be tested with CTI's ladar system against simplified targets and help validate assertions about sensor ATR effectiveness. System level requirements and methods for the ATR process will be developed to lead to real target simulators and ATR in Phase II.
