A phased array was recently assembled, calibrated and tested in two separate halves due to test facility limitations. This unique method has many advantages for future phased array production as it allows arrays of any size to be calibrated and tested to a very high accuracy, which results in decreased sidelobe level, beam pointing error, and increased directivity. This technique takes a major step...
For a planar, limited scan phased array with multiple grating lobes in real space, there are several potential sources of additional, anomalous far-field lobes which may be observed upon transformation of near-field measurement data collected during planar near-field scanning. If there is a constant leakage term present in the measurement receiver independent of the probe position, then a single leakage...
