Apparatus and method of CRPA neutralization for illegal unmanned aerial vehicle

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.

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.
