Scalable Integrated RF Current Source

Vadum will develop an innovative, efficient, high power, and versatile Scalable Integrated Magnetic Sensing System (SIMSS) that will deliver superior performance to the warfighter by increasing the field strength for deeper magnetic detection. By augmenting ground-penetrating radar (GPR) with SIMSS, metal and low metal mine detection, command wire, pressure plate detection, and explosive cache detection will be significantly improved. The novel approach attains high performance and low cost by co-designing and integrating the high efficiency RF current source with a high-power transmit (Tx) loop, including a differential receiver (Rx) loop and circuit, and optimizing back-end signal generation and processing. This scalable approach accommodates a range of loop sizes, can be incorporated into a larger array, and is realizable as a dismount system. Increased standoff while minimizing electric field and resulting propagating wave allows for more sensitive human-safe detection applications as well as data disruption systems including camera capture denial and memory device erasing. The Phase II deliverable will be a TRL 5/6 prototype SIMSS sensor module demonstrating deep detection of objects.
