Abstract

The authors delineate some considerations in achieving RSL (range sidelobe) suppression in wideband phased arrays. Attention is given to wideband radar characteristics suppression of spurious signals, and sources of wideband RSLs. It is suggested that the parallelism associated with the transmitter and antenna paths should mitigate associated uncorrelated time-varying error modulation. The exciter can be a major RSL contributor unless spurious signal suppression with the SSBM (single sideband modulator) is emphasized in design and calibration procedures
