Design of error tolerance of a phased array
WebFeb 3, 1990 · The performance of planar phase-array antennas with mechanical errors is investigated. Errors in array element positions as a result of structural distortions are considered as deterministic and predictable. Detailed calculations for two assumed modes of distortion reveal that their effects on antenna performance are the loss of peak response … WebNov 16, 2024 · You may want to check the spacing of the array and the sampling rate. The GCC algorithm essentially does a correlation between channels. If your propagation speed relative to the spacing and the sampling rate is too high, then essentially the signal across two channels look the same and the correlation will start to give you dubious answers …
