The government would like to explore the applicability of LADAR to support future MDA missions. Key requirements are radiation hardening (LEO and lower MEO), singe photon sensitivity centered at 1.064 µm, range in the hundreds of km. To address this need, the Nu-Trek Team is proposing to develop LADAR/RH. It is based on an InGaAsP/InP linear-mode avalanche photodiode (APD). The key innovations include (1) A new low, multi sampling ROIC that is required to achieve near single photon sensitivity, range, and precision; (2) Parametric SEE hardening methodology; and (3) Use of a linear-mode InGaAsP/InP APD with low radiation susceptibility due to reduced active (absorber) device volume.
