1. A mobile decontamination system disposed as a mobile cart for treating contaminated surfaces disposed external to the system, the system comprising:
one or more on-board tanks for storing a directed energy enhancer (DEE) formulation in each tank;
a sprayer subsystem comprising a plurality of nozzles removably connected to a fluid manifold and in fluid communication with the one or more on-board storage tanks to spray the DEE formulation at a predetermined spray rate and substantially coat the contaminated surfaces to form coated surfaces, wherein the orientation of the nozzles is adjustable;
a radio frequency (RF) subsystem comprising a microwave generator configured to generate microwave radiation of predetermined frequency;
a plurality of pyramidal horn antennas to direct the microwave radiation to the coated surfaces, wherein the orientation of the antennas is adjustable;
a mobility subsystem comprising at least one of an undercarriage having wheels powered by a motor, computer vision, GPS, ultrasonic proximity sensors, optical sensors, sonar sensors, and gyroscopes and a robotic platform control system;
a power supply; and,
a control system disposed in bi-directional communication with the sprayer subsystem, RF subsystem, mobility subsystem, and power supply wherein the control system is configured to first spray the DEE formulation to substantially coat the contaminated surfaces, wait for a predetermined hold time, and then direct the microwave radiation to the coated surfaces, wherein the one or more on-board tanks, the sprayer subsystem, the radio frequency subsystem, the mobility subsystem, the power supply, and the control system are housed in the mobile cart.
