"Ok kids, can anybody tell me how many Surface to Air radar stations were bombed in the Balkan peacekeeping campaigns?" Julie asked the class.
"All of them?" A young kid who looked like a typical computer geek answered with a raised eyebrow.
"Sort of." Julie smiled. "The answer really is, anything that was turned on got bombed. Including cheap Chinese manufactured microwave ovens with a hole drilled in the door. Open fields with some old farm equipment, tarps, and logs could become an airfield. Space heaters could become a Command Post on a mountain side. Decoys, dummies, and battlefield clutter were only limited by the imagination of the planners."
"Right," The kid smiled, looking at his chart of wavelengths, "because the average household microwave shares the same wavelength as an S Band radar, and a commercial microwave oven in the L Band."
"Very good." Julie replied as the rest of the class gazed on with a glassy look in their eyes.
"Remember, we've covered the triangular ambush for low flying rotary wing aircraft." Julie lectured, snapping some of the students out of the overdose induced haze. "Remember, provide a threat in three directions and overwhelm the pilots OODA loop so that they can't make a good decision?"
"Right," A middle age man spoke up, "So instead of overwhelming a low flier with bullets, we overwhelm a high flyer with SAM alerts?"
"Right, imagine you are up there, where no small arms fire can reach you, and your radar warning system starts flashing L band and S band SAM warnings?" Julie asked, noting all the students eyes bright with attention now.
"I'd probably crap myself and start pumping chaff and flares." A bearded man in spoke for the first time.
"And that is why we are learning how to make decoy SAM RADAR sites." Julie replied. "Open your texts to page 47 to see examples of radar main reflectors that you can easily replicate with sheets of plywood and camouflage paint. Think about what emitters we can gather on the open market to replicate the signal output, and what timing devices we can use to replicate a duty cycle."
"Remember, every bomb or HARM that blows up a decoy is tens of thousands of dollars not being spent bombing actual humans." Julie lectured. "You have 15 minutes to choose a system to duplicate in wood, and conduct an initial sketch and materials list." She clicked her stopwatch, "Go."
