Claim 0:
1. An apparatus of controlled reception pattern antenna (CRPA) neutralization for an illegal unmanned aerial vehicle (UAV), the apparatus comprising:
an interference signal generator transmitting a direct wave toward a CRPA of an illegal UAV through a first transmission antenna and transmitting a first reflected wave inducing signal through a second transmission antenna; and
a first passive propagation mirror reflecting 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.
