Abstract
Architectures and techniques for radar signaling in emergency scenarios. A high-frequency radio signal in a first frequency range from a remote device with a local radio frequency (RF) receiver. The received radio signal in the first frequency range is converted to a corresponding signal in a second and lower frequency range. Signal phase information in the lower frequency signal is modified to generate a modified signal in the lower frequency range. The modified signal in the lower frequency range is converted to the first frequency range. The modified signal in the first frequency range is transmitted to the remote device with an RF transmitter.
Claims19
A system comprising:
- a radio frequency (RF) receiver to receive a radio signal from a remote source;
- a signal augmentation agent coupled with the RF receiver to modify signal phase information in the received radio signal based on one or more emergency parameters to generate a modified signal in response to a detection of an emergency condition;
- and
- a radio frequency (RF) transmitter coupled with the signal augmentation agent to transmit the modified signal, wherein the modified signal is indicative of the emergency condition.
A non-transitory computer-readable medium having stored thereon instructions that, when executed by one or more processors, are configurable to cause the one or more processors to:
- receive, with a radio frequency (RF) receiver, a high-frequency radio signal in a first frequency range from a remote device;
- convert the received radio signal in the first frequency range to a corresponding signal in a second frequency range that is lower than the first frequency range;
- modify signal phase information in the corresponding signal to generate a modified signal in the second frequency range, wherein the modification is enabled in response to detection of an emergency condition;
- convert the modified signal in the second frequency range to the first frequency range to generate a high-frequency modified signal;
- and
- transmit, with a radio frequency (RF) transmitter, the high-frequency modified signal in the first frequency range to the remote device, wherein the high-frequency modified signal is indicative of the emergency condition.
