The block diagrams of active receiving digital and analog ultra-wideband video pulse scanning antenna array (VPSAA) containing the beam control system (BCS) and low-noise amplifiers, which inputs are connected to ultra-wideband radiators in every channel of the array, are presented. The basic elements of digital BCS are analog-digital converter in every channel of the array and digital processing device; and of analog BCS - device of discrete delays (DDD) in every channel delaying the received signal by a required value, combiner of signals of VPSAA channels, and programmable control device providing the setting of the required delay values in channels and their delivery to DDD. Analog DDD can be electronic and optoelectronic. The optoelectronic BCS includes also the transmitting optoelectronic module in every array channel converting the signal from radio frequency range into optical range, optical combiner and receiving optoelectronic module performing the inverse signal conversion by frequency. The block diagram of optoelectronic BCS containing the optical beam former and multichannel optical switch is presented. This BCS fulfills scanning of VPSAA beam without application of the controlled DDD; multi-beam receipt could be also provided. The parameters of BCS basic elements of receiving VPSAA are given. It is noted that traditional radio pulse receiving phased arrays could be built on its basis. In this case one and the same ultra-wideband receiving modules could be used in phased arrays of different wavelength ranges permitting to unify the modules or their components for wide class of receiving antenna arrays. The experimental research results of the optoelectronic BCS elements for receiving VPSAA are considered. The conclusion is made on possibility to design the active ultra-wideband receiving VPSAA on the basis of digital devices, analog DDD and optical beam former with multichannel optical switch.
