ABSTRACT:
1. A system of recording the passage of a vessel through a harbor entrance omprising a first plurality of equally spaced devices arranged transversely of the harbor entrance, said devices being adapted to respond to the potential field of a vessel as the vessel moves adjacent thereto, a second plurality of similar devices in alignment with the first devices and spaced midway therebetween respectively, third and fourth pluralities of similar devices alternately spaced midway between said first and second devices respectively and in alignment therewith, a pair of means respectively connected to said first and second and said third and fourth devices for receiving a response signal from said first and second devices and simultaneously receiving a response signal from said third and fourth devices respectively as the vessel moves adjacent thereto, means connected to said pair of means for adding said response signals together to produce a resultant signal, and recording means responsive to said resultant signal for producing a record indicative of the amplitude thereof.
