description The invention discloses a phased array overall situation focusing system and a focusing method thereof. The phased array overall situation focusing system can transmit on a single energy converter unit by turns and all the energy converter units receive and focus transmission and receiving synthesis on echo line scanning signals of a plurality of sampling points of a space, so that the space imaging quality can be greatly improved. The phased array overall situation focusing system comprises an energy converter unit, a signal processing unit, a dynamic delay overall situation focusing compensation module and a signal overlapping module; the phased array overall situation focusing system can be used for transmitting the phased array and focusing the transmission and receiving synthesis on any one space point on a synthesis line behind a space initial focusing point; in an ultrasonic phased array control nondestructive testing application, the echo line scanning signals reflected by a pre-set sampling point wit
