Claim 5:
6. An apparatus of controlled reception pattern antenna (CRPA) neutralization for an illegal unmanned aerial vehicle (UAV), the apparatus comprising:
a first interference signal generator installed in a first area;
a first passive propagation mirror installed in a second area;
a second interference signal generator installed in a third area; and
a second passive propagation mirror installed in a fourth area,
wherein the first interference signal generator transmits a first direct wave toward the CRPA of the illegal UAV and transmits a first reflected wave inducing signal toward the first passive propagation mirror so that a first reflected wave propagates toward the CRPA of the illegal UAV, and
the second interference signal generator transmits a second direct wave toward the CRPA of the illegal UAV and transmits a second reflected wave inducing signal toward the second passive propagation mirror so that a second reflected wave propagates toward the CRPA of the illegal UAV.
