Claim 8:
9. A method of CRPA neutralization for an illegal unmanned aerial vehicle (UAV), the method comprising:
transmitting a direct wave, by an interference signal generator installed in a first area, to a CRPA of an illegal UAV and transmitting a first reflected wave inducing signal to a first passive propagation mirror installed in a second area; and
reflecting, by the first passive propagation mirror, the first reflected wave inducing signal toward the illegal UAV so that the first reflected wave propagates toward the CRPA of the illegal UAV,
wherein the first passive propagation mirror is configured to rotate a reflector in an azimuth direction with respect to a first axis and tilt the reflector in an elevation direction with respect to a second axis.
