TOYON RESEARCH CORPORATION — Department of Defense SBIR Phase I: A17-134

Description

Unsecured areas contain multiple threats. These threats include unknown radio frequency (RF) transmissions that could exist anywhere in the 2 MHz to 6 GHz frequency range. To assist in securing the area, there is a desire to detect, identify, locate, and potentially disrupt these RF transmissions. Due to the physical threats in the environment, a solution that can provide intelligence of the RF transmissions via one or more unmanned ground vehicles (UGVs) is desired. In this environment there will be multiple signals to process, each with different RF characteristics. The UGV may have line-of-sight access to a transmitter, or the UGV may receive the RF transmission after it has taken multiple different paths. Toyon proposes to use our multiple input/multiple output embedded software defined radio product to implement an automatic RF scanning system covering the frequency range of 1 MHz to 6 GHz. This system will also be configured to identify the type of RF transmission it detects. Direction finding (DF) algorithms and antenna designs will be studied along with methods for Electronic Attack directed toward the detected transmission. A prototype system design will be developed during the Phase I effort, and fabricated and demonstrated during the Phase II program.
