FIELD: antenna assemblies for directional radiation and reception.
SUBSTANCE: all radiated power is used in each direction (in each beam) but at different frequencies; each beam is probed within time interval depending on signal length multiplied by relative duration of probing pulse; echo signals of all beams are received simultaneously as they arrive and separated into beams by means of filters mounted at output of active phased antenna array adders. Beams are independently controlled by means of beyond-module sets of controlled phase shifters. Each set is designed for control by separate beam.
EFFECT: enhanced radiation power of each independently controlled beam, enhanced precision of measuring target angular coordinates.
