Method and apparatus for calibrating phased array receiving antennas |
摘要 |
Disclosed is a method and apparatus for calibrating phased array receiving antennas that includes circuitry for generating a pair of calibration signals separable one from the other. The signals are injected into the delay elements of the antenna from opposite ends of a complementary calibration cable. The delay produced in the calibration signals is individually measured, and the delays summed and averaged to produce a delay measurement independent of delays produced by the calibration cable and accordingly delay measurement variations caused by environmental effects on the calibration cable.
