Abstract

Systems and methods for embedding a warning signal in a sensor pulse. When a taxi anticollision system of a host aircraft senses a threat headed for the aircraft, a warning signal is embedded in a sensor pulse to warn the offending vehicle that it is in the field of view of the host aircraft'"'"'s sensor and is moving on a trajectory that is threatening collision with the host aircraft. Alternately, the radar issues a dedicated pulse for reading and alerting the receiving device.

Claims

1. A device comprising:

at least one antenna;

an RFID device in signal communication with the at least one antenna, the RFID device configured to provide identification information via the at least one antenna in response to a read pulse received at the at least one antenna;

a receiver in signal communication with the at least one antenna;

a processor configured to

receive a signal from the at least one antenna;

determine whether identification information included in the received signal matches identification information of the RFID device; and

if the identification information of the received signal matches the identification information of the RFID device, generate an alert signal; and

an output device configured to provide an alert based on the generated alert signal.

2. The device of claim 1, wherein the processor is further configured to

determine status of the receiver;

and

deactivate the RFID device if the status of the receiver is in at least one of an off state or a standby state.

3. The device of claim 1, wherein the device is located on a vehicle.

4. The device of claim 3, wherein the vehicle comprises an airport support vehicle.

5. The device of claim 3, wherein the vehicle comprises an aircraft.

6. A device located on a host vehicle, the device comprising:

a transceiver; and

a processor coupled to the transceiver, the processor configured to

transmit a read pulse via the transceiver;

receive a return signal based on the read pulse;

determine whether a target identified by the return signal is on a collision course with the host vehicle;

determine whether the return signal includes identification information; and

generate a warning signal if the target and the host vehicle are determined to be on a collision course,

wherein the transceiver is configured to transmit the warning signal,

wherein the warning signal comprises the identification information if determined to be included in the return signal.

7. The device of claim 6, wherein the processor determines whether a target identified by the return signal is on a collision course with the host vehicle by tracking the target, based on a plurality of received return signals.

8. The device of claim 6, wherein the device is located on a vehicle.

9. The device of claim 8, wherein the vehicle comprises an aircraft.

10. A method performed by a device having at least one antenna, an RFID device, a processor and an output device, the method comprising:

at the at least one antenna,

receiving a read pulse;

at the RFID device in signal communication with the at least one antenna,

providing identification information via the at least one antenna in response to a read pulse received at the at least one antenna;

at the processor,

receiving a signal from the at least one antenna;

determining whether identification information included in the received signal matches identification information of the RFID device;

if the identification information of the received signal matches the identification information of the RFID device, generating an alert signal; and

at the output device,

outputting an alert based on the generated alert signal.

11. The method of claim 10, further comprising at the processor:

determining the status of a receiver coupled to the at least one antenna; and

deactivating the RFID device if the status of the receiver is in at least one of an off state or a standby state.

12. The method of claim 10, wherein the device is located on a vehicle.

13. The method of claim 12, wherein the vehicle comprises an airport support vehicle.

14. The method of claim 12, wherein the vehicle comprises an aircraft.
