Coherent Array Telescope for Nanoradian Remote Sensing
Abstract
We propose the Coherent Array Telescope for Nanoradian Remote Sensing. The Coherent Array Telescope 1.0 (CAT1) will be an array of 8 2.5-meter focal length f-# near infrared telescopes design for snapshot array imaging and scatter ptychography. Snapshot array imaging uses neural inference to combine coherently combine images from the array to create a greater than1 meter synthetic aperture. Nonlinear estimation of moving objects captured on such an array may resolve images at ranges of greater than10 km with greater than100 nanoradian instantaneous field of view (ifov). The proposed array has 0.5 m2 full aperture. Tomographic imaging of scatter from remote objects with the light collection capacity of the array may enable scatter ptychographic imaging with nanoradian ifov. The goal of CAT1 is to be enable the first greater than10 km range demonstration of such resolution, which is approximately1000x greater than current practice conventional telescopes. CAT1 will be constructed at the University of Arizona and operated in the 1.- micron wavelength band at Arizona field sites.
