As a matter of fact, I have, and it was not a pleasant experience.
OTOH, sidewinder sensitivities must be set for the jet range, which is several thousand degrees hotter.
If you set the homing device to a lower temperature, I'm sure it would have a hard time acquiring the right target (a 200 ºC source at 1 Km must not be very distinguishable from the solar heat, but I'm just guessing).
Anyway, "it's just a movie, for god's sake! (tm)"
