The receiver of the Type 965Q and 965R used "a coherent oscillator (COHO) to provide the coherence in phase between transmission and reception. The COHO is phase locked to the transmitter pulse." With the Type 965Q and 965R, the pulse repetition frequency (PRF) had a number of different settings.
717:(page 13) explains that Type 42 destroyers were equipped with "UAA1 (Abbey Hill)" from 1978, and says that this is a type of electronic warfare equipment it calls "intercepts", which "detect and identify the radars of approaching aircraft, ships and missiles."

The Type 965 radars used radio frequencies that were used by television stations, and therefore caused interference with television (and vice versa) if used near land in Europe. Type 965 was superseded by the

A common aerial was used for transmitting and receiving. This was the single bedstead AKE(1) in the Type 965M, and the double bedstead AKE(2) in the Type 965P. The 965M and 965P were integrated with
