Statistical Modeling of Phased Arrays

Virtual EM Inc.’s software product VirAntenn-Array™ was developed as part of Phase III contract from REMEC Defense & Space, Inc. (now Cobham plc) for analyzing complex phased array architectures. The software will be used to simulate the complete phased array operation of the 2×2 subarray complete with power divider, attenuator and phase shifter/true-time-delay-units (TDUs). VirAntenn-Array ™ is also capable of predicting the effect of manufacturing tolerances such as element position errors, temperature gradients, RMS delay errors and predicts the resulting degradations such as beam pointing errors, beam squint and higher side lobe levels (SLLs).
