You are already tracking the birds. You are just choosing to ignore them. Here is an idea that ESC people rejected—have a computer do the search without driving the display screens to filter out the birds and civil aircraft and look for other anomalies. If that requires changing search fences, so be it. After all, isn’t that what we pay those jamokes at whatever they are calling ESC these days to do?
No. A track is different than a low level detection. Tracks are processed and require specially scheduled track pulses. If we tracked birds, we would not radar transmitter energy or processing power to do anything else.
