The present invention relates to a detector that detects a transmitted digital signature using the energy output from a matched filter. The energies are tabulated according to an anticipated signature pattern for variable transmission distances. The tabulation accounts for expected round trip transmission delays and allows processing of the accumulated symbols to derive a correct signature whether coherent or non-coherent signature coding is used and multiple Doppler channels are present. <IMAGE>
