$745,147Benefit:
Assuming a successful completion of the proposed research and development there are several potential beneficial results. Receiver systems in many applications require increasing bandwidth while maintaining or increasing their linear dynamic range. Military systems that may benefit include radar systems for which increased linearity (or reduced) spurs represent the ability to detect and estimate smaller or farther targets while minimizing false alarms. SIGINT systems will be able to detect small signals of interest in a wide spectrum in the presence of strong interfering signals on smaller platforms. Commercial uses for such applications include incorporating such approaches into systems built by large defense manufacturers. For civilian applications the expected benefits of the research and development proposed here will allow receiver systems such as future cellular base stations to operate in increasingly crowded spectrum without having to resort to using ever shrinking cells and over wider bandwidths.
