Modern - as in cutting edge technology - it might not be, but so far as the sensors being integrated into ACCS and compared to the current inventory, acquiring the TPS-77 and having the sheer chutzpah to get the racketeers of the energy industry to pay for it is not a bad bit of business.
It has rightly been observed that there would have only been one other way we would have got hold of such technology and that would have been the day that Satan took delivery of his first pair of ice skates.
Lets just hope that joe public doesnt catch on to the fact that both the "renewable" energy industry and the acquisition of these radars may have involved quite a number of er... players, shall we say telling slightly less than the whole truth.
Amazing what you can get away with these days.
