Long Distance LADAR (LIDAR) Systems and Methods

The US Army seeks a partner to license and commercialize methods for improved long distance laser detection and ranging (LADAR) systems.

The Technology: 

The US Army has developed a ladar system to provide unambiguous range and velocity measurements of long distance targets such as sea-skimming anti-ship missiles. By using the ladar's range and velocity data, false alarms and clutter objects will be distinguished from incoming missiles at longer ranges (up to 10 km). Because the developed ladar uses an array receiver, it can also provide three-dimensional (3-D) imagery of potential threats at closer ranges (2-3 km) in support of the force protection/situational awareness mission. 
The US Army inventions incorporate a chirped amplitude modulation (chirped AM) architecture, a Doppler tracking method using photonic mixing detectors and other techniques for enabling active LADAR and high resolution imagery. The US Army patents in this area will primarily benefit systems that employ a photocathode imaging tube.

Benefits: 
  • Distinguishes long distance targets (10 km) while eliminating false alarms and clutter objects
  • Provides three-dimensional (3-D) imagery of potential threats at closer ranges
  • Ability to acquire, process, and display 3D imagery in near real-time, including near real-time frame-to-frame re-registration to compensate for platform and target motion.
  • Improved LADAR design with greater modulation depth across the chirp bandwidth, a more compact chirp generator, and improved thermal management
The Opportunity: 
  • Collection of three (3) patents available as a portfolio¬†
  • Potential for collaboration with US Army scientists and laboratory
