ABSTRACT:
A correlator arrangement for a radar fuze (FIG. 1) in which the outgoing signal is modulated with a reference code and the incoming echo correlated with the code to pick out the signal. To reduce the effect of Doppler frequency modulation there are means 15-18 to reduce the frequency of signals outside a predetermined frequency range to bring them within that range.
