Abstract:
1. A correlation system, comprising: a transmitter configured to transmit a correlation sequence; receive circuitry configured to receive returns from the transmitted correlation sequence; a plurality of correlators coupled to the receive circuitry and configured to correlate the correlation sequence with the returns to provide a set of correlation measurement values respectively associated with the returns, wherein the set comprises a respective correlation measurement value from each of the correlators, each of the correlation measurement values corresponding to a respective distance from the transmitter and indicative of a condition at the corresponding distance, wherein one of the correlation measurement values associated with one of the returns is corrupted by error from a plurality of the returns; and a correlation error compensation (CEC) element configured to receive the correlation measurement values and to adjust the one correlation measurement value based on a plurality of the correlation measurement values thereby compensating the one correlation measurement value for the error.
