Abstract (en)

In the or each steered adaptive control processor loop with weight update gain of an adaptive antenna system is included a weight limiting network (11), which serves to put variable, but equal, bounding limits to each individual inphase and quadrature component of each adaptive weight, whereby to limit the growth of output noise in the presence of a misaligned signal whilst maintaining sidelobe jammer suppression capability.
