Title:  Adaptive Multiwaveform Laser Ranging and Detection (LADAR)
Research & Technical Areas:  Sensors, Electronics

  Objective:  Develop an adaptive multiwaveform LADAR sensor that can generate arbitrary optical waveforms customized to meet a wide variety of target sensing requirements.
  Description:  Previous laser ranging and detection systems have utilized a simple optical pulse train for target sensing. Only the power, pulse-width, and repetition rate could be changed. This limits the amount of information that can be recovered from a target scan. Recent advances in photonics technology now make it possible to add further dimensions to laser radar sensing. The LADAR waveforms can be changed in real time to increase target detection and identification performance. By varying the waveform’s temporal amplitude, phase, polarization, and frequency content, future LADAR sensors will be able to detect additional target characteristics as well as operate effectively under challenging environmental conditions. Increased resolution from tailored waveforms will also aid in the identification of friendly forces, distinguishing them from noncooperative targets, leading to higher confidence before allowing lethal strikes. Combined with advanced signal processing, this will open a new generation of smart LADAR sensors capable of conducting a broad range of terrestrial and aerospace surveillance, identification, targeting, assessment, and force protection missions.

  PHASE I: Develop and evaluate a compact multiwaveform LADAR sensor design. This should include modeling and laboratory experiments to clearly establish sensor feasibility.
  
  PHASE II: Fabricate a prototype multiwaveform LADAR sensor and demonstrate its adaptive operating characteristics on a moving platform in a simulated field environment. Report all technology development and test results. Analyze potential product opportunities for synthesized waveform LADAR sensors. Deliver a transition plan describing the timetable, resources, and activities necessary for transition.

  DUAL USE COMMERCIALIZATION: Military application: Target detection/identification/tracking/designation; optical countermeasures; search and rescue; chemical detection; antiproliferation and treaty compliance; and Homeland Security sensing. Commercial application: Medical diagnosis; environmental monitoring; natural resources exploration; transportation safety; industrial security; space exploration.
