Adaptive Multiwaveform Laser Ranging and Detection (LADAR)

An Adaptive Multiwaveform (AWF) LADAR design will be developed; the critical technological components tested; characterized and laboratory experiments conducted and modeled to clearly establish feasibility. In Phase I, using high-speed InGaAs and electron-initiated avalanche photodiodes (eAPDs) and high performance amplifiers, the combined effects of varying the waveform’s temporal amplitude, phase, polarization, and frequency content and the APDs temporal response will be characterized. A completed end-to-end system model will be developed using existing analystical, Monte Carlo, and atmospheric-predictive codes. Additionally, during Phase I, the compact AWF-LADAR sensor design will be detailed, and all of the critical technologies, including the adaptive space-to-time RF-photonic waveform generator, will be demonstrated in the laboratory. This will allow a fully-functional prototype to be built and tested in simulated field environments. The effort’s overarching goal is to optimize small-sized low-cost AWF-LADAR sensors capable of both detecting additional target characteristics and efficient operation under challenging environmental conditions. The-AWF-LADAR will also aid in identification and discrimination of friendly forces from noncooperative targets, leading to high-confidence strikes. Advanced signal processing enable 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.
