Determining a location of a runway based on radar signals

A method comprising:

• causing a radar device to transmit first X-band radar signals in a weather mode;
• causing the radar device to receive return X-band radar signals reflected off weather formations in the weather mode;
• causing the radar device to transmit second X-band radar signals at a first frequency in a landing mode;
• causing the radar device to receive, in the landing mode, reply X-band radar signals transmitted by a transponder at a second frequency in response to the second X-band radar signals transmitted by the radar device, wherein the second frequency is offset from the first frequency;
• detecting, in the weather mode, the weather formations based on the return X-band radar signals received by the radar device;
• determining, in the landing mode, a position of the transponder based on the reply X-band radar signals received by the radar device;
• and
• determining a location of a runway based on the position of the transponder.

A device comprising a computer-readable medium having executable instructions stored thereon, configured to be executable by one or more processors for causing the one or more processors to:

• cause a radar device to transmit first X-band radar signals;
• cause the radar device to receive return X-band radar signals reflected off weather formations;
• cause the radar device to transmit second X-band radar signals at a first frequency in a landing mode;
• cause the radar device to receive, in the landing mode, reply X-band radar signals transmitted by a transponder at a second frequency in response to the second X-band radar signals transmitted by the radar device, wherein the second frequency is offset from the first frequency;
• detect, in a weather mode, the weather formations based on the return X-band radar signals received by the radar device;
• determine, in the landing mode, a position of the transponder based on the reply X-band radar signals received by the radar device;
• and
• determine a location of a runway based on the position of the transponder.
