Abstract
A frequency characteristic for a compression filter is synthesized which is optimal in terms of resolving multiple coherent signals with different amplitude-phase relations and delays. A formula is derived for calculating the signal-to-noise ratio at the filter output for a sum of coherent signals. It is shown that with the right choice of compression parameters it is possible to exclude entirely the effect of the amplitudephase relations on resolution of the signals.
