Imagine you are sitting on a chair at the edge of a large lake on a pitch black night, overcast with no stars. There are no visual references to use for range estimation. A boat somewhere out on the lake flashes a torch briefly and the person on the chair has to calculate the range of the boat from the chair to an accuracy of 1 meter. There are no other people on chairs on the lake that can also give information, just you on your chair, possibly with one eye closed. This highlights the technical challenges we have overcome using this invention.
Now imagine there are 50 boats out there scattered randomly, who all flash their lights briefly and are expecting their location to be identified.
Now imagine all the boats start moving and you have to track their individual paths while sitting on your chair.
Despite this large amount of source information, the calculations are done in the reader and the reader can condense the information on each target to identity and coordinate details only so as not to overload the computer network.
