What are your plans for adjusting to evolution in sensor defeating technologies deployed by Santa? Are reports of his radar cross section reducing each year accurate? Has there been any success in drone deployed IRST assets to determine the efficiency of Claus's propulsion system?

I'm working on the operating theory that Santa is not primarily a physical phenomenon, as the energy expenditure from his travel should have significant effects on atmospheric conditions as yet unseen, and so the radar trace monitored by NORAD is a distraction. An adjustment of Santa's EW capabilities evolving in lockstep with the development of sensor technology would, given Claus's clear advantage in technological development, be supportive of such a counter intelligence strategy. If I had to guess, there has been no relative change in sensor signal responses from Santa over the period of this tracking program.
