I'm writing a report to see if it's feasible to power a secondary surveillance radar with wind energy. I'm having trouble with sizing the turbine but I can't seem to find an energy demand for a SSR anywhere. any help is appreciated.
What you propose is possible. TCAS is essentially a secondary surveillance radar, and is a piece of avionics which doesn't break the bank power wise. In a moderate traffic environment, I have seen 3 to 5 amps at 24VDC. I am sure it is higher in a dense environment. The interrogation power requirement doesn't go up but processing the returns may take more power.
5 amps at 24VDC is a modest power requirement for a mid-sized wind energy system, therefore at first blush, what you propose is quite possible.
