ABSTRACT:
A rotating antenna system subject to both tilt and translation forces includes first and second tilt sensors each having a pendulum assembly of a different length than the other sensor. The sensors provide identical output signals in response to a tilt, but different output signals in response to a translation of the antenna. Circuitry is provided for eliminating the effects of translation so as to obtain a tilt angle correction signal for correcting the radar height calculation.
