The problems of design of signal aperture processing systems in adaptive antenna arrays (AAA) providing a receiving of wide-band signals at the background of multiple high-intensity jamming are considered.

It is shown that the basic approach to solve such problems is to combine the use of analog devices constructed with the aid of modern low-noise broad-band technologies of microwave and digital systems of signal processing and information storage.

The comparative analysis of variants of combined systems of aperture processing by the criterion of approximating their characteristics to the Wiener filter algorithm in a wide dynamic range of input signals and coordination of adaptation process with the rate of data arriving, updating and processing is carried out.
