Pioneered by the defence department's Joint Non-Lethal Weapons Program (JNLWD), the new direct energy weapon has the ability to stop a cart in its tracks without harming the vehicle or its driver.
"The jammer works by targeting the car's engine control unit causing it to reboot over and over, stalling the engine. Like an invisible hand, the microwaves hold the car in place." David Law, who leads JNLWD's technology division, said in March: "Anything that has electronics on it, these high-powered microwaves will affect. As long as the [radio] is on, it holds the vehicle stopped."
[...] "The RFVS system uses high-power magnetron tubes to generate intense RF pulses that interfere with a vehicle's electronics, rendering it temporarily inoperable. The engine cannot be restarted while the RF is on but is readily restarted once the RF is turned off. Thus, the RFVS system allows for the maintenance of a safe keep-out zone in situations that might otherwise require the use of lethal force. The defined measure of success for this system is a demonstrated, effective capability against more than 80% of the candidate target-vehicle-class list, which includes passenger cars and large vehicles."

The satellite dish will reflect it, but not 'back'. It will be reflected toward the focal point (assuming the axis of the dish is aligned with the emitter). Once the reflected energy passes through the focal point, it will continue outward in a wide conical pattern.
