Automatic Radar Plotting Systems

Extract

If I may continue Mr. Harrison's analogistic extravaganza for only a moment, I would like to say that whatever smoke, haze or fog there may have been in his vicinity it has prevented him from identifying the target at which I and my colleagues have been firing. I must also say that his bland assumption of the superiority of his own gunnery is hardly complimentary to the highly qualified and experienced support without which, as he well knows, no simple sailor would venture into such a technical action.

None of my comments made upon this subject thus far have denied the existence of errors, cyclic or otherwise, in the sources from which the radar data is drawn; nor have I disagreed with the evidence and the theories about the size and character of such errors, and the resulting prediction errors they might cause, which have been adduced by the various experts (in electronics), under the conditions and within the limits which they postulate.
