Research Institution
To address the Army"s need to greatly reduce the occurrence or magnitude of intermodulation products in electromagnetic environment (EME) generation systems, Physical Optics Corporation (POC) proposes to develop a new methodology for Mitigation of Intermodulation Spurious Signals Produced in Electromagnetic Environment Generation Systems (MISSPEL). This proposed approach is based on real time pre-distortion using physics-based models of RF power amplifier nonlinearity along with novel signal processing algorithms. The innovation in the methodology and algorithms will enable MISSPEL to offer over 20 dB reduction in intermodulation spurious signals within the 1 MHz3 GHz band. MISSPEL offers automated, real-time mitigation of intermodulation products in EME generation systems, which directly addresses the Electronic Proving Ground (EPG) requirements to be readily adaptable to existing RF amplifiers and current EPG operations. In Phase I, POC will demonstrate the technical feasibility and technological viability of MISSPEL through hardware and software prototyping. In Phase II, POC plans to develop a hardware field programmable gate array (FPGA)-based prototype and demonstrate to the government the desired performance enhancement.
