SIMULTANEOUS MULTI-FREQUENCY SIGNAL PROCESSING METHOD |
摘要 |
A method for the simultaneous multi-frequency signal processing within a single receiver is presented. The pulse compression or filtering method samples the received signal at a data rate commensurate with the maximum frequency separation of waveforms at separate frequencies being received, but the compression calculations are only performed at a rate commensurate with the bandwidth of each individual transmit waveform set. The method reduces the processor requirements for extracting all available information from these signals. |

1. A method for processing multiple signals of interest in a single receiver, for which the signals are of different frequencies, the method comprising the steps of:
a) receiving an analog signal Z comprising a combination of at least two waveforms of arbitrary bandwidth X and an arbitrary center frequency separation Y; b) digitally sampling said analog signal at a rate at least equal to the Nyquist frequency Y+X; and c) digitally pulse compressing the samples using sample rates at lest equal to the Nyquist frequency Y+X, but performing the calculation at a lower frequency rate X that is consistent with the Nyquist frequency of the individual waveform. |
