Abstract
In response to the Army need, Physical Optics Corporation (POC) proposes to mature, in Phase II, the new methodology for Mitigation of Intermodulation Spurious Signals Produced in Electromagnetic Environment Generation Systems (MISSPEL) developed and proven feasible in Phase I. Up to 30 dB in-band reduction of intermodulation products (IMP) up to 7th order were demonstrated in Phase I by applying a prototype MISSPEL system with 1 GHz bandwidth to a commercial-off-the-shelf (COTS) broadband power amplifier. No additional in-band spurious signals are introduced, and the fundamental signals remain unaffected, ensuring the high fidelity of the approach. In Phase II, fully automated prototype systems will be developed based on two implementations of the MISSPEL methodology: (1) a stand-alone software toolkit that analyzes a known signal script and generates a modified signal script that will yield greatly reduced IMP; and (2) a real-time hardware toolkit that can reduce IMP in a free-play scenario of random signals. The performance enhancement offered by the MISSPEL prototypes will be evaluated and demonstrated to the government. Successful demonstration of these prototype implementations, which are easily integrated with current Army Electronic Proving Ground (EPG) test operations, will ensure rapid transition to production-ready capability in Phase III.
