Abstract

A novel architecture for a ladar transceiver is proposed to achieve high-resolution imaging and precision tracking of complex targets. This architecture combines a conventional imaging receiver (telescope) with a noncoherent sparse array of photon buckets into one system. The diffraction limited resolution of the array exceeds that of the telescope. This ladar architecture is designed to use a new technique, CRITIC, which is based on combining the relevant information obtained simultaneously with the telescope and the array. In particular, the CRITIC technique allows one to overcome :several drawbacks of conventional monostatic ladars and opens new prospects for both the ground- and space-based ladars.
