Abstract: Admiral Graham has covered the subject of Harbor Radar Systems in a very able manner. The following comments are offered with the idea of endeavoring to clarify a few points which might be misunderstood or misinterpreted. The statement that the French Government, after 3 years of trial operation of a shipboard type radar, and after thorough evaluation of the needs, has purchased the first especially engineered harbor radar for the Port of Le Havre is no doubt the case-as far as the Port of Le Havre is concerned. However, it is worthy of note that a specially designed radar for the Port of Liverpool was placed in operation in July 1948. Its special console-type indicator includes a total of 6 specially designed radar scopes, 4 of which cover overlapping sectors of the harbor, the fifth the entire harbor, and the sixth is used as a "wandering" scope which can be used to inspect any particular sector or overlapping sectors desired. This 3 cm installation includes a 15-foot scanner and provides a bearing resolution better than 0.75 degree.
