The invention discloses a digital beam forming technique verification system which comprises a main control calculation module, a transfer storage control module, a high-speed storage module, an AD (Analogue/Digital) acquisition module and a power supply module, wherein the main control calculation module is connected with the transfer storage control module by virtue of a PCIe (Peripheral Component Interface Express) bus; the high-speed storage module, the AD acquisition module and the transfer storage control module are interconnected by virtue of in-plate high-speed buses. A data processing method comprises the following steps: synchronously acquiring an external simulation signal, a triggering signal and an external supply clock input signal; rapidly storing the acquired data by adopting a high-speed storage technique; performing replay processing and file management on the stored data according to demands by a user, and performing deletion, reading and formatting operations; correcting mistakes of data codes in real time, and correcting random BIT mistakes generated in the programming process by using a BCH (Broadcast Channel) mistake correction encoding technique. By adopting the digital beam forming technique verification system, functions such as synchronous acquisition, storage, replay and processing on multi-channel signals are achieved, the application range is wide, and the data storage and transfer storage stability and the data storage speed are improved.
