Multi-band Range and Doppler Processing Using S2-CHIP Technology

The scope of this proposed effort is to design and demonstrate a multi-band (S and X), wide instantaneous bandwidth (>1 GHz S-band and >2 GHz at X-band) range processor utilizing S2-CHIP technology. S2-CHIP, termed for spatial spectral coherent holographic integrating processor, is an analog optical signal processor that has the ability to process coherent multi-band, ultra-wide-bandwidth radar return signals in real time for range and Doppler target discrimination and identification. The proposed proof-of-concept demonstration, along with device modeling and analysis, will show the capability of the S2-CHIP technology to simultaneously process these bands in one volume of S2 material and provide validated projections of the performance of such an ultra-wideband coherent processor. We will work with MDA on important system specifications, such as types of broadband codes, bandwidths and RF frequencies, as well as to identify system critical performance metrics. Utilizing current S2-CHIP models, we will simulate our systems specific performance and compare it with demonstrated results. Under Phase II we will begin design and development of a full system prototype that will enable multi-band range and Doppler extraction.
