The French fighter Rafale uses active cancellation to confound radar detection. Reflected wave Emted wave It sends out a signal that's one half a wavelength out-of-phase with the radar wave it reflects. The reflected and emitted waves cancel in the direction of the enemy receiver. This is the consequence of the superposition of two waves that travel slightly different distances in the same direction. Find the mathematical expression and explain the phenomena. What measure should you do to detect the fighter Rafale? What if more than one Rafale fighters attack?
