Don't make a big deal on your precious radar, it won't stop the government hitting it's renewable obligations. NATS and the MOD will always object where they feel they need to. Radar is really not a big issue for the consultants that design them. The visual aspect is the killer, but even chopped up raptors will drop a wind farm dead far easier. The masses don't care for radar returns, only their easy-appreciated views.
One of said consultants, not yet had a windfarm dropped on radar grounds (3+ yrs).
PS. If you don't want one, go and rent a few great crested newts the day before the site gets an ecology survey.
