Representative independent claim 16 is reproduced below:
16. An underwater detection system for detecting underlying transient objects and underwater
conditions comprising:
ship position measuring means for successively measuring a position of a ship and for producing
position signals;
radiating means for successively radiating search signals into a body of water to search for
underlying transient objects and underwater conditions;
receiving means for receiving echo signals, said echo signals being search signals reflected from
the underlying transient objects and the underwater conditions;
first memory means for storing said position signals from said ship position measuring means;
second memory means for storing said echo signals representing the underlying transient objects
and underwater conditions;
said radiating means and receiving means forming an active continuous real-time sonar system
while the ship is operating;
reading means for reading the stored signals from said first and second memory means;
an indicator for displaying the stored signals from said first memory means to form a track of the
ship, said track of the ship representing a plurality of points corresponding to past positions of the ship,
for displaying a present position of the ship, and for displaying the stored signals from said second
memory means to show underwater conditions and underlying transient objects corresponding to the
present position of the ship on two corresponding portions of a display face of said indicator means,
said display face being divided into two parts;
selecting means for selecting any past point along the track of the ship; and
