A phase independent digital correlator for use in radar systems comprising a signal input circuit, a multiplying stage, a plurality of combination devices, an integrating circuit, a plurality of threshold devices and a signal output circuit. The multiplying stage comprises at least one pair of 90.degree. phase-shifted multipliers. The combination devices, coupled between the multipliers and the integrators, form linear combinations of the product signals produced by the multipliers. The threshold circuit comprises a plurality of inputs that are coupled to separate integrators.
