Science Daily  August 2, 2023 An international team of researchers (Israel, USA – University of Rochester, Canada) studied the fundamental underpinnings of range resolution in coherent remote sensing. They used a novel class of self-referential interference functions to show that they could greatly improve upon currently accepted bounds for range resolution. They considered the range resolution problem from the perspective of single-parameter estimation of amplitude versus the traditional temporally resolved paradigm. They defined the minimum resolvable distance between two depths and the depth resolution between the objects as two figures of merit. They experimentally demonstrated that their system could resolve […]
