Abstract
Embodiments regard techniques for mitigating radio frequency interference (RFI) in weather data. A method includes receiving raw pulse returns, censoring the raw pulse returns to alter data of the raw pulse returns that is affected by the RFI resulting in censored pulse returns, compressing the censored pulse returns resulting in censored, compressed pulse returns, and transmitting, by an antenna, the censored, compressed pulse returns.
Claims18
A device comprising:
- processing circuitry;
- a memory including instructions that, when performed by the processing circuitry, cause the processing circuitry to perform operations for radio frequency interference (RFI) mitigated weather pulse returns, the operations comprising:
- receiving raw pulse returns from a weather radar;
- censoring the raw pulse returns in a frequency domain, by removing, altering, and replacing the raw pulse returns that are affected by the RFI resulting in censored pulse returns, wherein censoring includes comparing an amplitude of a current cell to an average amplitude of a specified number of cells that are directly adjacent to the current cell;
- and
- compressing the censored pulse returns resulting in censored, compressed pulse returns;
- and
- a channel configured to digitally transmit the censored, compressed pulse returns.
A method for generating radio frequency interference (RFI) mitigated weather data, the operations comprising:
- receiving raw pulse returns;
- censoring the raw pulse returns in a frequency domain by removing, altering, and replacing the raw pulse returns that are affected by the RFI resulting in censored pulse returns, wherein censoring includes comparing an amplitude of a current cell to an average amplitude of a specified number of cells that are directly adjacent to the current cell;
- and
- compressing the censored pulse returns resulting in censored, compressed pulse returns;
- and
- digitally transmitting the censored, compressed pulse returns.
A non-transitory machine-readable medium including instructions that, when executed by a machine, cause the machine to perform operations for generating radio frequency interference (RFI) mitigated weather data, the operations comprising:
- receiving raw pulse returns;
- censoring the raw pulse returns in a frequency domain by removing, altering, and replacing the raw pulse returns that are affected by the RFI resulting in censored pulse returns, wherein censoring includes comparing an amplitude of a current cell to an average amplitude of a specified number of cells that are directly adjacent to the current cell;
- and
- compressing the censored pulse returns resulting in censored, compressed pulse returns;
- and
- digitally transmitting the censored, compressed pulse returns.
