Abstract
Spatial-spectral holographic materials enable the development of microwave photonic devices that can perform a variety of demanding microwave signal processing functions, including spectrum analysis, signal correlation, time-difference of arrival measurements, and first pulse signal capture. This paper summarizes the recently published advances in the technology, which include demonstration systems with over 20 GHz of instantaneous bandwidth with sub-MHz resolution, over 60 dB of spur free dynamic range, and time-difference-of-arrival geolocation of emitters down to the sub-foot level.
